+Subject: [PATCH] [cmake] Append -Wl,-rpath-link conditionally to GNULD
+
+Append -Wl,-rpath-link conditionally to whether GNU ld.bfd is used
+rather than the Linux+!gold conditionals. Also move it out of 'else'
+branch of *BSD handling. This fixes build failures with ld.bfd
+on Gentoo/FreeBSD, and should cause no harm on other systems using
+ld.bfd.
+
+This patch improves the original logic by reusing results of linker
+detection introduced in r307852.
