Darn.  Well, let me use this opportunity to ask, how are folks doing
32-bit cross builds on Fedora?  I used to keep an i686 PAE VM for this
purpose, but I was eventually no longer able to maintain the build
dependencies.  Looks like this failed on a mipsel cross build, but I
don't see such a cross compiler in Fedora.  I do mingw32/64 cross
builds, but they leave a lot to be desired for code coverage.  Thanks,
