Most printer drivers compile model-specific PPDs from a generic schema
during the build process, using ppdc, the PPD compiler. ppdc must be
able to find CUPS' internal include files, which are architecture-
independent and can be used from sysroot-host.
Unfortunately, the CUPS build system is rather inflexible, so we have to
build the whole core distribution to get a working ppdc.

Notes:
changes in v1 -> v2:
- remove unused code in host-cups.make
- compile ppdc in compile stage, not in install stage
- use @$(call compile) and $(call install), not $(MAKE) directly
- use --exec-prefix=/ and --libdir=/lib/ to get rid of LD_LIBRARY_PATH
- set CUPS_DATADIR in sysroot-cross wrapper, so an additional include path
is
no longer needed, and ppdc also doesn't look for files on the host file
system!
- make clean stage more silent
