The background here is that we encountered many painful build problems
with qt-4.7 on mips64 in oe-core-1.2. We tried to fix them initially
but investigations from 6 months ago indicated that the qt upstream
did not support mips64. Kai will dig into the current situation
but I expect that little will have changed.

We ended up with horrid bbapends such as:
---
#Valid for all arches except mips64 with 64bit userspace
# mips64 with n32 has host: mips64-wrs-linux-gnun32
# mips64 with n64 has host: mips64-wrsmllib64-linux
# qemumips has host: mips-wrs-linux
# qemumips-64 has host: mips64-wrs-linux
COMPATIBLE_HOST = 
'((x86_64.*|i.86.*|powerpc.*|arm.*|mips-.*|mips32.*)-linux|mips64.*-linux-gnun32)'
---

so we'll likely need a clue on how to declare a host as incompatible
or introduce an INCOMPATIBLE_HOST variable.
