Subject: [PATCH 0/2] objtool: fix libelf detection in non-standard locations
Date: Fri, 23 Feb 2018 15:22:13 +0100	[thread overview]
Message-ID: <cover.1519393674.git.robin.jarry@6wind.com> (raw)

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,
