Subject: [PATCH 0/3] HOSTCFLAGS and HOSTLDFLAGS from the environment
Date: Wed, 28 Mar 2018 17:48:02 -0700	[thread overview]
Message-ID: <20180329004805.7278-1-labbott@redhat.com> (raw)

Hi,

Someone noted that scripts/tools userspace binaries packaged as part of
the Fedora kernel were not picking up the recommended compiler flags
(https://src.fedoraproject.org/rpms/redhat-rpm-config/blob/master/f/buildflags.md)
This series lets the host ld and C flags be set on the command line
similar to the kernel flags:

make AFLAGS_HOSTCFLAGS="%{build_cflags}" AFLAGS_HOSTLDFLAGS="%{build_ldflags}"

There's one more annoying case I didn't quite figure out with
tools/objtool/fixdep since that's linked with ld directly but this
covers the initial set of reports.

Thanks,
Laura
