ispc: fix run_tests.py test script

Some testcases are currently failing with following error:
/usr/bin/x86_64-poky-linux-ld: ./tests/static-array-init-1.ispc.o:
relocation R_X86_64_32S against `.rodata.cst16' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/x86_64-poky-linux-ld: failed to set dynamic section sizes: bad value

Backport patch.
