Hack round the FreeBSD iconv support in Freebsd 10. In 10 libc now
supports iconv however iconv.h is present under /usr/local.
Start to add support to build qemu for MinGW via a Cxc. This is a
work in progress and contains lots of hidden traps.
In config.py separate out of the canadian build status.
Qemu requires gettext, glib, libffi, and pixman. DTC is built
as a submodule.
On Mavrick provide a pkg-config command so avoid needing a pkgconfig.
The one here is only just good enough to work.
Provide an internal autotools build including libtool so qemu can
be built from git.
Rework the RTEMS build set files to point to the new location.
Move the files into devel, this follows the ports naming in
FreeBSD.
Update the macros, defaults, and options to support this.
