Because meson does not provide a simple way to get the relative build path, it is computed with a pair of foreach loops. As meson does not have a simple way to compute string length (except via underscorify and 63 split operations), the build script uses a shell command instead. If the compiler does not suppot -fmacro-prefix-map, then fall back to passing in the relative path prefix, and use its length to offset the uses of __FILE__ in log messages so that the build path is at least still not included in the logs. This is significantly more efficient than calling _sway_strip_path.
