Kbuild, lto: add ld-version and ld-ifversion macros To check the linker version. Used by the LTO makefile.

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 ...")

ld-version: Fix it on Fedora 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. Signed-off-by: Michael S.
