[GTK] Respect PKG_CONFIG env variable when generating gtk-doc

[Erik van Pienbroek]

The tool generate-gtkdoc internally calls pkg-config.
When cross-compiling it shouldn't use pkg-config, but
it should use the pkg-config which was detected by
the ./configure script (for example this can be
i686-w64-mingw32-pkg-config when cross-compiling)

Can be simplified into:
pkg_config = os.environ.get('PKG_CONFIG', 'pkg-config')
