-Subject: [PATCH] Revert "Use pcfiledir for prefix in pkgconfig file"
-
-The change makes implicit assumptions on the layout of the install
-tree, which is going to break in many ways.
-
-The correct solution is to use the `PKG_CONFIG_SYSROOT_DIR` variable
-to inject the cross-compiled sysroot into `-I` and `-L` paths.
