Subject: [PATCH 0/2] objtool: fix libelf detection in non-standard locations

When libelf headers and libs are not in standard locations, the check
fails and host flags are ignored.

I have encountered this issue when building linux into the buildroot
framework. host-* versions of libs may be compiled and installed in a
host staging dir removing the need to install them on the build system.

Comments are welcome.

Regards,
