+$libdir isn't used by the Makefile at all apart from in this mkdir.
+This will be used without any DESTDIR so if your libdir is a different
+layout to the bulid system it will cause a failure. E.g:
+
+Build system has /usr/lib only
+libdir = /usr/lib64 for the target
+Results in "mkdir: cannot create directory `/usr/lib64': Permission denied"
+
+Since the directory is never used, we can just remove the mkdir.
