I'm sure someone will correct me if my information is out of date, but
last I knew cross-compiling of packages was essentially impossible.
The basic problem is that most packages rely on autoconf (or similar)
configure scripts to determine the flavor of the target host. Examples:
where is libtermcap? is strtok_r(3) present?
It's possible to build a cache of the "right" answers and make configure
pay attention to it, and that will get you partway home, but you'd still
be a long way from cross-building /usr/pkgsrc.
The NetBSD build framework OTOH does not interrogate the build system for
target-host facilities. Complete information is provided by the config
file and the secure, simplifying knowledge that the target system will be
running NetBSD.
