Subject: [PATCH] Autotools: fix: do not put '$prefix' based paths in
 compilation flags

This was causing problems with cross-compilation with a dedicated sysroot,
because compilation would incorrectly use headers and libraries from the
`--prefix` path. The `--prefix` path is meant to indicate a target path to
install to, not a path from which to source dependent libraries.
