When cross-compiling, it's common to have executables prefixed with the name of the architecture you're building for, e.g. aarch64-unknown-linux-musl-cc or x86_64-unknown-freebsd-pkg-config. Lots of build tools support a PKG_CONFIG environment variable to enable this use case. With this change, I was able to successfully cross-compile and run catgirl.
