hermiticity issues in scripts/kconfig/ and arch/x86/tools/

[nickdesaulniers]

I have some hacked up broken version of clang; but I noticed that an LLVM=1 build is producing errors from /usr/bin/ld which was unexpected:

/usr/bin/ld: scripts/kconfig/lexer.lex.o: warning: relocation in read-only section `noreturn_fns'

nevermind the specific error message; it's the invocation of /usr/bin/ld for those inputs that's unexpected.

Isn't this #479? Those are both host programs, so it is going to use the default linker of HOSTCC, unless HOSTLDFLAGS=-fuse-ld=lld is used.

ah, right
