ld-version: Fix awk regex compile failure
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: ccbef1674a15 ("Kbuild, lto: add ld-version and ld-ifversion ...")
