uClibc doesn't implement __register_atfork() on noMMU systems, causing
a build failure of libressl. Since openssl is available as an
alternative on such platforms, we just disable libressl on
uClibc/noMMU systems.
Fixes:
/home/thomas/projets/buildroot/output/build/libressl-2.5.5/crypto/.libs/libcrypto.a(arc4random.o): In function `_rs_init.part.1':
arc4random.c:(.text+0x74): undefined reference to `__register_atfork'
collect2: error: ld returned 1 exit status
This build issue is not visible in the autobuilders, because libressl
is only selectable through a choice, which isn't randomized by the
autobuilder logic.

At this point, libressl can be added to the openssl virtual package.
- Remove the entry package/libressl/Config.in from package/Config.in
- Remove the file: package/libressl/Config.in
- Add libressl entry to package/openssl/Config.in

Some packages that use openssl are not compatible with libressl, only
with the real openssl (known as libopenssl in Buildroot). So before we
add libressl as a provider for the openssl virtual package, we
introduce a BR2_PACKAGE_OPENSSL_FORCE_LIBOPENSSL hidden option that
packages incompatible with LibreSSL will be able to select.
This will allow packages that need OpenSSL to continue using "select",
without having to change to using "depends on" dependencies.

To ease the transition to having both OpenSSL and LibreSSL, there has to be
a new virtual package introduced to handle both.
Instead of making a libssl, and adding OpenSSL and libressl to that package,
it will be far easier to move openssl to libopenssl and to make OpenSSL
a virtual package. This offers a few advantages:
- BR2_PACKAGE_OPENSSL is still a visible symbol with no dependencies.
- It does not require a huge patch to convert every instance of
OpenSSL -> libssl)
- Users will be able to update without ever having to select anything new.
- LibreSSL can be added at a later date to the virtual package.

The dependency doesn't make sense now that the option only controls if the
built binary gets installed into the target or not, so drop it.

Now that building the openssl binary without MMU is supported, the only
reason left for not building apps if the openssl binary is disabled is
to save build time. Moreover, the commit
720893b625 "openssl: disable apps for
NOMMU", which added this behavior, had a side effect: the scripts from
apps (CA.pl, CA.sh and tsget) and the default configuration file
(openssl.cnf) were no longer installed, which is not advertized by the
BR2_PACKAGE_OPENSSL_BIN option. CA.pl and CA.sh use the openssl binary,
so not installing them without the latter makes sense. But tsget does
not use the openssl binary, and openssl.cnf can be used by libcrypto, so
it is preferable to handle BR2_PACKAGE_OPENSSL_BIN like before the
commit mentioned above, i.e. to always build and install apps and to
just remove the openssl binary afterwards if needed.
This is what the current commit does, but installing only the helper
scripts having their dependencies (perl or the openssl binary)
satisfied. The help text is updated accordingly.

The commit 720893b625 "openssl: disable
apps for NOMMU" prevented the openssl binary from being built without
MMU in order to fix a build failure without fork(). However, openssl is
designed to support the lack of fork() with -DHAVE_FORK=0, so allow the
openssl binary to be enabled without MMU thanks to this option.

In the Config.in file of package foo, it often happens that there are other
symbols besides BR2_PACKAGE_FOO. Typically, these symbols only make sense
when foo itself is enabled. There are two ways to express this: with
depends on BR2_PACKAGE_FOO
in each extra symbol, or with
if BR2_PACKAGE_FOO
...
endif
around the entire set of extra symbols.
The if/endif approach avoids the repetition of 'depends on' statements on
multiple symbols, so this is clearly preferred. But even when there is only
one extra symbol, if/endif is a more logical choice:
- it is future-proof for when extra symbols are added
- it allows to have just one strategy instead of two (less confusion)
This patch modifies the Config.in files accordingly.

Enable OCF (cryptodev) support for openssl as an option.
This requires a patched kernel to export hardware acceleration for
openssl to use it.
If you lack a patched kernel or support it won't break anything, it will
simply fall back to the default software engine from openssl, you'll
just have a slightly bigger libssl/libcrypto.

If I understand you correctly, you want the ncurses development headers
on the target.
a patch for this (named target_headers.patch and includes similar
options for a few other libs in buildroot) can be found at:
http://www.zelow.no/floppyfw/download/Development/Patches/buildroot/
(a few packages there aswell)
it will add an option to put headers on target for ncurses, zlib and
openssl.
