Clang and NetBSD/ARM

Following the recent flag day to move (e)ARM from EHABI to normal Itanium-style unwinding as well as the import of recent LLVM/Clang, the EABI variants of the ARM ports are now fully supported with Clang. In short, just setting MKLLVM=yes and HAVE_LLVM=yes for will switch to over to the BSD licensed toolchain. Testing especially on ARMv4 is very welcome.

Martin Husemann is stitll working on the networking support for the Cubietruck, but once that is done we plan to setup a bunch of Cubietruck boards for bulk building pkgsrc. Stay tuned.

I'm investigating MIPS now, but that is a bit more tricky.
