So I've applied, but there were a number of issues left:

 - It didn't build with uClibc or musl, due to the use of argp, which
   is a glibc-only feature. I had to add a dependency on
   argp-standalone and pass -largp in the linker flags on musl ||
   uclibc configurations.

 - On uClibc, it still wasn't building due to a <personality.h> value
   missing, and another <elf.h> value missing.

 - The --without-libstdc++ was not really appropriate, as we do have
   C++ support in Buildroot obviously.

Do not hesitate to check the final commit to make sure I didn't mess up
anything. Thanks a lot!
