commit: http://git.buildroot.net/buildroot/commit/?id=7d6e415cc91912a8314ef91abe47396ba5ad49dd
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

For 32 bit archictectures the luajit package needs a host compiler
able to generate 32 bit code using the "-m32" option so check if that
option is supported.
