don't require pkg-config in wsl-as-helper build

windows build doesn't make use of system libraries, so we only need to
make autoconf/configure happy (allow it to use PKG_CHECK_MODULES macro)
but for that adding the m4/mac path is enough (there's nothing mac
specific, just the pkg-config macros have been added for mac initially)
