[oe] [jalimo-info] problems with latest openjdk - fixed

[Xerxes Rånby]

Hi Pete

I have back-ported fixes to the oe.dev llvm2.7 from the upstream
llvm2.8svn branch to fix the
"ARMCodeEmitter::emitPseudoInstruction  UNREACHABLE executed at
/OE/angstrom-dev/work/armv7a-angstrom-linux-gnueabi/llvm2.7-2.7-r6/llvm-2.7/lib/Target/ARM/ARMCodeEmitter.cpp:554!"
that you have been hitting.
http://cgit.openembedded.org/cgit.cgi/openembedded/commit/?id=d1dcd08e4ec0b65aaaef149bace47da16acf7626

Using these back-ports the "whet" test-case runs fine on my overo earth
summit armv7 test board:
I have been using openjdk-6-jre-6b18-1.8-r8.6 in combination with
llvm2.7-2.7-r7 from oe.dev.
