[PATCH] A little fix for configure script

[Валентин]

Hello! 

Script "configure" uses "pkg-config" directly (at line 2420), which always takes GLIB_VERSION from host system. 

In case of cross-compilation, it should use "$pkg_config", to take GLIB_VERSION of cross-compiled glib (as it is used earlier at line 1476).

So, the line:

echo "GLIB_VERSION=$(pkg-config --modversion glib-2.0)" >> $config_host_mak

should be:

echo "GLIB_VERSION=$($pkg_config --modversion glib-2.0)" >> $config_host_mak

With best regards,

Valentine.
