This patch is spamming compiles with unhelpful and confusing messages. E.g. the Linux kernel uses "grep -q" in several places. It's meant to quit with a return code of zero when the first match is found. This can cause a SIGPIPE signal, but that's expected, and there's no way to turn this error message off to avoid spurious error messages. UNIX03 apparently doesn't require printing an error message on SIGPIPE, but specifically when there's an error on the stdout stream in a normal program flow, e.g. when SIGPIPE trap is disabled. A separate patch is planned to address the specific case we care most about (involving llvm-nm). This reverts commit b89bcef.
