That's why you should cross-compile. The SIP/PyQt build system does not
support cross-compilation, but it can be achieved, by manually editing the
generated Makefiles.

For instance, for SIP, it is sufficient to modify siplib/Makefile and
replace all occurrences of gcc/g++/strip with your cross toolchaing (eg:
arm-gcc, arm-g++, arm-strip). Of course, you might also need to add some
standard include/library paths (if your toolchain doesn't add them already)
and flags like "-msoft-float" or similar, but you get the idea. You don't
need to modify sipgen/Makefile of course, since you need a sip binary for
the host computer, not the target.

I think that the correct fix would be to modify SIP's configure to support
two different platforms: host and target (the former used to build sipgen,
the latter for siplib).
