-      First fix a problem with glibc-2.36:
+      Some packages checks on the phrase <literal>gccgo</literal> in the output
+      of <command>go version</command> to see which kind of Go compiler is
+      installed (gcc-go or golang). The absence of <literal>gccgo</literal> in
+      that string makes them to assume the compiler is the golang which is wrong.
+      If Go isn't in the list of desired languages, this patch can be skipped
+      while it does not harm if applied anyway. Fix the Go part of gcc to show
+      a valid version string when calling <command>go version</command> by
+      applying a patch:
