linkers_detect: detect xtools (Apple ld64 derivative)

xtools is in use on Gentoo Prefix x86_64 and ppc based Darwin installs.
Pick it up as a valid linker.

Since xtools is answering with a version to --version, as opposed to
ld64, detection of xtools in the ld64 handling block is not possible,
since --version already succeeded.
