When building modules with a native le toolchain the linker will
generate R_PPC64_TOCSAVE relocations when it's safe to omit saving r2 on
a plt call. This isn't helpful in the conext of a kernel module and the
kernel will fail to load those modules with an error like:
nf_conntrack: Unknown ADD relocation: 109This patch tells the linker to avoid createing R_PPC64_TOCSAVE relocations allowing modules to load.
