clang regression testing if failling.

Kristof Beyls via cfe-dev
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:   

Invoking the compiler as /home/exaleapserver/ws/khan/tools/LLVM/Basic-llvm/Exe-linux/bin/clang --static /home/exaleapserver/ws/khan/tools/LLVM/test/clang-regression/clang-tests/gcc-4_2-testsuite/src/gcc.apple/special/liblongcall.c   -dynamiclib -mlongcall -DNO_TRAMPOLINES -fno-show-column     -g    -o /home/exaleapserver/ws/khan/tools/LLVM/test/clang-regression/September_26_2019/wrkdir/gcc.apple/special/liblongcall.dylib
