Subject: [Qemu-devel] [PATCHv2 RFC] makefile: detect corrupted elf files
Date: Wed, 22 May 2013 01:07:09 +0300	[thread overview]
Message-ID: <20130521220709.GA26328@redhat.com> (raw)

Once in a while make gets killed and doesn't
clean up partial object files after it.
Result is nasty errors from link.
This hack checks object is well formed before linking,
and rebuilds it if not.

Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

v1 actually prints some noise on stderr, this shuts it up.
