caddfa6237 Revert "gnutls: drop wchar dependency"
This reverts commit 694cdb9273.

Just like commit 68c3f5257d (Revert "gnutls: make it non-wchar
friendly") before. It turns out that gnulib expects some other library
to provide a wctomb() implementation. So when the C library does not
provide one it is left as undefined symbol in libgnutls.so.

Add a comment to reduce the chance of repeating the same mistake again.

694cdb9273 gnutls: drop wchar dependency
Commit 19448f40a0 (gnutls: use included unistring unless libunistring is
selected) made libunistring an optional dependency.  So now gnutls no longer
depend on wchar.

Drop wchar dependency of libmicrohttpd and libsoup, which are gnutls
reverse dependencies that do not depend themselves on wchar.

Update the comments in libsoup and taskd; the wchar dependency is now
not due to gnutls.

30ed9de2fd package/gnutls: disable for static build
The gnutils code uses __attribute__((constructor)) and
__attribute__((destructor)) to call constructor/desctructor when a
shared library is loaded.
Constructor/desctructor are not used when a static library is used
(except when if -Wl,--whole-archive -lgnutls -Wno-whole-archive is
used, not tested).

Even if gnutls initialization (_gnutls_global_init()) may be
called manually, the gnutls maintainer said it's not supported [1].

"Note that static linking applications with gnutls is not something
 supported. gnutls relies on library constructors and destructors
 which are not loaded when linking statically."

Now the gnutls script warns about static linking [2].

So disable gnutls statically by adding "depends on !BR2_STATIC_LIBS"
at Kconfig level and --disable-static in GNUTLS_CONF_OPTS.

5c5077e117 package: update comments for reverse dependencies of util-linux
Commit 006a328ad6 ("util-linux: fix build with ncurses") removed
dependency on BR2_USE_WCHAR, but failed to update the reverse
dependencies of util-linux.

This commit updates comments in Config.in for BR2_USE_WCHAR for reverse
dependencies of util-linux which directly uses wchar now or when it is
pulled from other dependencies.

eudev doesn't use wchar directly, but needs C99 compiler. Autotools
generate code with wchar_t for checking C99 compiler.

[Thomas:
 - use 'depends on' for BR2_USE_MMU, and add a comment indicating that
   the dependency is due to the use of fork()
 - use 'depends on' for BR2_USE_WCHAR, and add a comment indicating
   that the dependency is due to gnutls and util-linux.
 - add a hash file.]
