I agree, we should not be be multiplying hacks.  There is already code
adding -Wl,--build-id=none to TARGET_LDFLAGS.  It's a macro
grub_PROG_LD_BUILD_ID_NONE in aclocal.m4.  What's wrong with it?  Does
it fail to add -Wl,--build-id=none on PowerPC or is TARGET_LDFLAGS not
used to link kernel.elf?

What are the symptoms caused by not using -Wl,--build-id=none?
