If anyone has any objections, please let me know. ------------------ From: James Hogan commit 4b7b1ef2c2f83d702272555e8adb839a50ba0f8e upstream. 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.
