From f2dbe03dccc95f41429d60e4221b02fc0f112cc4 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 27 Feb 2008 11:42:15 -0800 Subject: [PATCH] x86 vdso: fix build locale dependency Priit Laes discovered that the sed command processing nm output was sensitive to locale settings. This was addressed in commit 03994f01e8b72b3d01fd3d09d1cc7c9f421a727c by using [:alnum:] in place of [a-zA-Z0-9]. But that solution too is locale-dependent and may not always match the identifiers it needs to. The better fix is just to run sed et al with a fixed locale setting in all builds.
