Subject: Commit 0d989ac2c90b broke my x86-64 build.

The attached config built fine before the above commit, doesn't build after. The
commit in question did nothing except remove support for building x86-64 without
libelf.

It took me a while to notice because the commit ONLY broke x86-64. I can still
build arm (32 and 64 bit), i686, m68k, mips/mipsel, powerpc, s390x, and sh4
without libelf in my cross compiler. Heck, I can still build i686. The change
seems to have added a unique build dependency to just x86-64.

P.S. Why do you need a special library to parse elf anyway? It's a fairly simple
file format, linux has include/linux.elf.h, the toolchain already has an objtool
prefixed for the appropriate cross compiler...
