dev-build/meson: backport macos Prefix fix

Followup to commit 791e631e0121da91676113928a3e4070453c2449. The patch
has been integrated upstream and will be backported to meson 1.3.2; the
issues with including it here have been resolved, so bring it back.

Closes: https://bugs.gentoo.org/868516

+Subject: [PATCH] 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.
