From: Sandipan Das <sandipan@linux.vnet.ibm.com>
As stated in tests/llvm-src-base.c, the name of the bpf function should be "bpf_func__SyS_epoll_pwait" but this clang test fails as it tries to lookup "bpf_func__SyS_epoll_wait".
Before applying patch:
55: builtin clang support : 55.1: builtin clang compile C source to IR : FAILED! 55.2: builtin clang compile C source to ELF object : Skip
After applying patch:
55: builtin clang support : 55.1: builtin clang compile C source to IR : Ok 55.2: builtin clang compile C source to ELF object : Ok
