- fall back to compile test for windows paffinity component
when cross compiling
- fall back to platform guess when checking for threads having
different pids with pthreads (yes on linux, no elsewhere)
- pass the proper host, target, and build flags to the
ROMIO configure script
With these changes, cross-compiling should be possible with the exception
of the Fortran 77 and Fortran 90 bindings. Fortran 77 can be cross-
compiled if cache values are provided for type sizes and alignment.
