QEMU build fails on OpenBSD/mips64

[Brad Smith]

Building QEMU 1.2.1 on OpenBSD/mips64 fails as follows although I believe QEMU was also broken with 1.1.x as well..

Strange. It was building with older releases and I'm fairly certain what
was built actually ran Ok. Looking at the MIPS TCG code it looks as if
there is some code in there to deal with 32-bit vs 64-bit MIPS.

Anyway, if the MIPS TCG code does not officially support 64-bit MIPS
then the build infrastructure should be fixed to not shoot people in
the feet trying to build QEMU. The 32-bit SPARC support needs to be
fixed too.

Triaging old bug tickets ... does this problem still persist with the latest version of QEMU (currently version 2.9.0)?
