On a system using new glibc that doesn't include RPC, and libtirpc as RPC
provider, a number of compiler-rt tests fail:

Failing Tests (4):
    MemorySanitizer-X86_64 :: Linux/sunrpc.cc
    MemorySanitizer-X86_64 :: Linux/sunrpc_bytes.cc
    MemorySanitizer-X86_64 :: Linux/sunrpc_string.cc
    ThreadSanitizer-x86_64 :: sunrpc.cc


The tests fail trying to find RPC headers without adding appropriate -I paths:

Command Output (stderr):
--
+ : 'RUN: at line 1'

A month ago, I've submitted two fixes for finding and using libtirpc which are
stuck in review:
