commit: http://git.buildroot.net/buildroot/commit/?id=02f5589d6fe85e73a965359f5dfa2a49930ae3e0
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next
gcc 4.6 has become more sensitive about option ordering, especially
libraries. It requires the -l flags to be placed after the object
files that need that library. See for example
http://nick.zoic.org/art/etc/gcc-linker-libs.html. We had -llua at the
beginning of the link command line, causing build issues (here on gcc
4.6 with host-lua).
