libguytools is mostly straight-forward C code, except for some
lines in backtrace handler (see  below).
I'm not sure if you could encounter little problems with header
files (surely nothing serious), I don't have experience with hurd
and kfreebsd.

Stack backtracking: Have a look at function ToolSignalBacktraceHandler
in toolsignal.cpp. I already made it architecture independant but I
never tried it on architectures like sparc, for instance.

However, I have an old PowerBook G4 at my disposal where succesfully
build libguytools and guymager powerpc packages. Just add "powerpc"
to the list of architectures in debian/control.

Adding other architectures: The function ToolSignalBacktraceHandler
should normally be the only one that needs to be adapted.
