Subject: [PATCH] Meta: Set proper PKG_CONFIG_EXECUTABLE and GN paths for
 aarch64 Linux

We need to avoid using vcpkg's pkg-config on non-x86_64 platforms,
because they do very strange things to the default paths.

On Asahi Linux and other 16 KiB page distros, the user must also provide
a properly compiled version of GN.
