The -nostdlib option requests the compiler to not use the standard
system startup files or libraries when linking.
arch/kvm/Makefile adds it to KBUILD_CFLAGS/AFLAGS, but it does not make
sense because those are unrelated to linking.
arch/{mips,riscv,x86}/Makefile passes it to the linker, but it is not
sensible either. As noted above, adding -nostdlib makes sense only
when $(CC) is used as a linker driver, but $(LD) is directly used for
linking barebox. (ld.bfd/ld.lld recognizes the -nostdlib flag, but its
behavior is obscure, and unneeded here.)
