Starting with glibc 2.25, the proc_service.h header has been copied from gdb to glibc so other tools can use it. However, that makes it necessary to make sure that declaration of prfpregset_t declaration is consistent between gdb and glibc. In gdb, however, there is a workaround for a broken prfpregset_t declaration in glibc 2.3 which uses AC_TRY_RUN to detect if it's needed, which doesn't work in cross-compilation. So pass the cache option to configure. It needs to be passed to GDB_CONF_ENV to build gdbserver only but also to GDB_MAKE_ENV, because otherwise it does not get passed to the configure script of nested packages while building gdbserver with full debugger.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
