The purpose of this is to provide some basic headers from glibc and
linux-headers like elf.h and byteswap.h that are not available on Mac OS.
It is not intended to be a replacement for all glibc API's, only enough to
cross-compile a linux kernel or to run make headers_install
By the way, linux's makefiles rely on gnu-only features of the following programs. You will want to have symlinks to the gnu versions of them in your path.
- expr
- sed
- stat
- xargs
