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 ...")

On Fedora 23, ld --version outputs:
GNU ld version 2.25-15.fc23
But ld-version.sh fails to parse this, so e.g. mips build fails to
enable VDSO, printing a warning that binutils >= 2.24 is required.
To fix, teach ld-version to parse this format.

The ld-version.sh script doesn't handle versions with large (>= 10) 3rd
version components, because the 2nd component is only multiplied by 10
times that of the 3rd component.
For example the following version string:
GNU ld (Codescape GNU Tools 2015.06-05 for MIPS MTI Linux) 2.24.90
gives a bogus version number:
20000000
+ 2400000
+ 900000 = 23300000
Breakage, confusion and mole-whacking ensues.
Increase the multipliers of the first two version components by a factor
of 10 to give space for a 3rd components of up to 99, and update the
sole user of ld-ifversion (MIPS VDSO) accordingly.
