Subject: [Buildroot] [PATCH] lvm2: disable PIE on ARC
Date: Wed,  1 Jul 2015 15:35:51 +0300	[thread overview]
Message-ID: <1435754151-23359-1-git-send-email-abrodkin@synopsys.com> (raw)

Even though ARC gcc understands "-pie" option and attempts to generate
PIE binaries as of today PIE is not really supported for user-space
applications.

So we disable PIE detection if building for ARC.
That first fixes http://autobuild.buildroot.net/results/988/9888a7a30538c9851f4910c16674d8dbb8edeb8f/
and also prevents execution of non-supported PIE binary in runtime.
