ld-version: Fix awk regex compile failure

Browse source 
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.

Fixes: ccbef1674a ("Kbuild, lto: add ld-version and ld-ifversion ...")
