Bill Wendling 4787efa380 Revert "Reapply: Add an error message to the default SIGPIPE handler" 
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 b89bcefa62.
