Thanks for providing these - they look great!

I have a few small requests:

+ namespace - in mk.conf can we prefix some of the more generic names
with PKGSRC e.g. PKGSRC_CROSS_COMPILE or PKGSRC_USE_CROSS_COMPILE
instead of USE_CROSS_COMPILE, etc. 

+ i think you mention somewhere that some form of cross pkg-config
is needed, but i'm having difficulty finding it now. sounds like this
would be a win.

+ we should note in the pkgsrc entry's Makefile that the entry is
cross-compilable (lesson learned from 14 years ago and adding
different OS support to pkgsrc). over time, this will hopefully be
less important, but in the early stages, it's a great way to identify
what needs to be done

Having said all that, these are truly minor concerns, and I would love
to see this in pkgsrc as soon as we possibly can. Pretty please?

Thanks,
Alistair
