Ah, I think the problem is that the build system is not playing nicely
with cross-compiles (which it looks like that's doing (specifically,
in that case, compiling for armv5 on an armv7 box)). I think an
immediate workaround would be to do ./configure
--host=armv5tel-unknown-linux-gnueabi or similar (in addition to
specifying the target -march). I think you'd need to specify the
--host in a similar manner for any cross-compile of Open MPI?
