Subject: [PATCH] buildsys: fix cross-compilation

Some identifiers for includes and libs paths may contain digit, e.g.
X11_PACKAGE or ATSPI2_PACKAGE or GLIB2_PACKAGE...

Also detect those identifiers when doing cros-compilation, so that the
_FOR_BUILD variants are really created and do not clash with the target
variants.

Fixes:
