Summary: - Fix test jump for powerpc64le Jumping directly to the return line on power architecture dos not means returning the value that is seen on the code. The last test fails, because it needs the execution of some assembly in the beginning of the function. Avoiding this test for this architecture. - Avoid evaluate environ variable name on Linux On Linux the Symbol environ conflicts with another variable, then in order to avoid it, this test was moved into a specific test, which is not supported if the OS is Linux. - Added PPC64le as MIPS behavior Checking the disassembler output, on PPC64le machines behaves as MPIS. Added method to identify PPC64le architecture and checking it when disassembling instructions in the test case.
