openjdk-6 shark build fails on amd64 allspice buildd

[Matthias Klose]

the openjdk-6 shark build fails in natty on the amd64 allspice buildd. both yellow and crested do build the package. the assumption is now that llvm-2.8 has a bug with the jit on this hardware. Not seen with builds using llvm-2.7 before.

this is seen on newer x86_64 hardware with llvm-2.8. I did verify that a 2.7 based build does succeed on the same hardware, so this looks like an issue in llvm-2.8. This hardware is only used as a buildd, I don't have remote access to it.

the build succeeds on:
model name : AMD Opteron(tm) Processor 246
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow rep_good

it fails on:
