When building gcc with "-pipe" in the C{XX}FLAGS, the following test suite
failures occur:

FAIL: 20_util/enable_shared_from_this/cons/constexpr.cc (test for excess
errors)
FAIL: 20_util/shared_ptr/cons/constexpr.cc (test for excess errors)
FAIL: 20_util/unique_ptr/cons/constexpr.cc (test for excess errors)
FAIL: 20_util/weak_ptr/cons/constexpr.cc (test for excess errors)
FAIL: 30_threads/future/cons/constexpr.cc (test for excess errors)
FAIL: 30_threads/shared_future/cons/constexpr.cc (test for excess errors)

This is because the following warning gets outputed:
g++: warning: -pipe ignored because -save-temps specified
