[ptxdist] [PATCH 6/7] host-cups: new package: CUPS PPD compiler

[Roland Hieber <r.hieber@pengutronix.de>]

Most printer drivers compile model-specific PPDs from a generic schema
using ppdc during the build process. For this, ppdc must be able to find
CUPS' internal include files in sysroot-target. Unfortunately, the CUPS
build system is rather inflexible, so we have to build nearly everything
to get a working ppdc.
