Host pkgconfig path will *always* be tried by pkgcofig; regardless of
setting of $PKG_CONFIG_PATH.

Use a target specific 'pkgconfig' tool (e.g. arm-xscale-linux-gnu-pkgconfig)
which is build with proper default searchpaths.  Hence, do not bother with
$PKG_CONFIG_PATH env, but change detection of pkgconfig executable so that
target binaries are preferred.
