Re: Add --enable-linker-version option

The recently-added ld-version*.d tests expect
.*GNU ld \(GNU Binutils\) 2.*
in the .comment section.

However, when buidling --with-pkgversion=XXX, we get
GNU ld (XXX) 2.[...]
instead, leading to a spurious FAIL.

This small patch replaces "GNU Binutils" with ".*" instead.

I inspected other testcases to see if we already had similar
occurrences but I couldn't see any, so I hope this fix is OK for the
purpose?

Thanks,

Christophe
