Hi Nitesh,

I tried to remove this MIPS specific code as it shouldn't be necessary if I add the above MergeFrom for all architecture but if I do it fails LinuxCore
TestCase.test_mips_n32.

The issue is that in that case the tripe we get from the core file is "mipsel--" ("mipsel--linux" after the merge) and the one we get from the binary is "mips64el--linux". Is it normal to have a seemingly 32bit core file with a 64bit binary on mips? If not then can I ask you to help me figure out which one is incorrect?

If it is then I don't see any better short term solution then leaving this condition here but it feels like a quite big hack what might backfire when somebody tries to use a core file with a completely incompatible binary.

Thanks,
Tamas
