This patch has been added to the 4.1 stable tree. If you have any objections, please let us know.
===============
[ Upstream commit 4b7b1ef2c2f83d702272555e8adb839a50ba0f8e ]
The ld-version.sh script fails on some versions of awk with the following error, resulting in build failures for MIPS:
awk: scripts/ld-version.sh: line 4: regular expression compile failed (missing '(')
This is due to the regular expression ".*)", meant to strip off the beginning of the ld version string up to the close bracket, however brackets have a meaning in regular expressions, so lets escape it so that awk doesn't expect a corresponding open bracket.
