Subject: [PATCH] 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.

Which tree should this be merged through? Mine? MIPS?
