H A DMakefile.build3b27a0c8 Thu Mar 03 11:39:30 CST 2016 Josh Poimboeuf <jpoimboe@redhat.com> objtool: Detect and warn if libelf is missing and don't break the build

With CONFIG_STACK_VALIDATION enabled, if the host system doesn't have
a development version of libelf installed, the build fails with errors
like:

elf.h:22:18: fatal error: gelf.h: No such file or directory compilation terminated.

Instead of failing to build, instead just print a warning and disable
stack validation.
