It is possible to cross compile NSPR, but I don't know how
to do that.

For Linux, prcpucfg.h is mozilla/nsprpub/pr/include/md/_linux.cfg.
_linux.cfg is renamed prcpucfg.h under the "dist" directory during
the build.

In _linux.cfg and _linux.h, there are sections specific to
various processors.  If the tensilica xtensa processor
isn't listed in _linux.cfg and _linux.h, you can search for
"arm" in those two files and add similar code for your
processor.
