That's very cool.  awk would do though :-)

That's not cross-compile friendly.  It may well be that crossbuilding
GNU Radio is already not doable, but it seems nice to avoid making it

NetBSD pkgsrc folks are thinking about how to make packages cross
building, so one could e..g build GNU Radio for sun3 or vax in a
reasonable time.  I relealize those are goofy examples, but it's nice
that the base system is cross buildable and it's occasionally annoying
that packages aren't.  Building for ppc or sparc64 on i386 is a less
goofy example.
