commit: http://git.buildroot.net/buildroot/commit/?id=aac3f315d9f4ec08728778e08a633f3b193522ed
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next
gcc5 defaults to -std=gnu11 which changes the inline semantics. This leads to
multiple definition error with 'extern inline'. See
https://gcc.gnu.org/gcc-5/porting_to.html for the details.
