clang regression testing if failling.

[cghalibkhan]

Hi,
To run test-suites of clang ,I followed these steps:

1. made a setup of clang tool-chain, After that cloned test suites from https://github.com/jpbonn/clang-tests.git and a frame-work of dejagnu,
2. written a machine board file riscv-sim.exp to dejagnu folder & site.exp to the test-suites folder where we want to run test-sites.
3. Run runtest driver, $ runtest --tool gcc
   Here i was getting around 18k linker errors.

• From those Errors, i have noticed that it was excepting some library. Please check in attached log

Could someone help me fix it?
Here is one analysis done on one test-case :
Run single test case to know whats the problem, with library,
$ runtest --tool gcc gcc.apple=liblongcall.a (Running in x86 ubuntu 16
Machine)

Error:
