Log Message:
Add a $(COPTS) variable to compile rules for passing options
seperately from ${CFLAGS}.  This is currently used to pass -prefer-pic
to libtool.  We indeed to prefer PIC, which is necessary to avoid
untoward relocs.

While here, make sure that PKG_DESTDIR_SUPPORT is set in a consisent
way from Makefile.lib.  This fixes a problem where it would become
unset under certain circumstances.

These packages are basically ready for import now, though
they do need more testing.
