Go for openwrt passes pkg-config arguments in the format of
pkg-config --cflags -- pkg-name
which in turn will be passed down to the real pkg-config as something
like
pkg-config.real --cflags -- pkg-name --define...
and causes the real pkg-config implementation to missinterpret the given
argument list.
This also helps to fix https://github.com/golang/go/issues/27940
