Technically, these files belong to the kernel, not glibc (but it does contain copies of these files).
Ideally, you should have a /usr/include/asm symlink pointing to /usr/src/linux/arch/powerpc (depending on your architecture and the location of your kernel-source),
and a /usr/include/asm-generic symlink pointing to /usr/src/linux/include/asm-generic (depending on the location of your kernel-source).
In this case file ppc_asm.h will be available as /usr/include/asm/ppc_asm.h
