+Subject: [PATCH 2/3] Allow Manual Overriding of pkg-config Lib and Include
+ Dirs
+
+When the `PCLIBDIR` or `PCINCDIR` is non-empty (either because we succeeded
+in removing the prefix, or because it was manually set), we don't need to
+perform the check. This lets us trust users who go to the trouble of setting
+a manual override, rather than still blindly failing the make.
+
+They'll still be prefixed with `${prefix}/` / `${exec_prefix}/` in the
+pkg-config file though.
