perf tests clang: Fix function name for clang IR test
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
