Together with unconditional stripping it breaks unwin= ding as used by pmcstat/dtrace or -fsanitize=3Daddress. Rather than add PROFILE = option let's use OPTIMIZED_CFLAGS to control vendor optimizations. But doing so induces POLA as -ffast-math from ports r69328 would contaminate defaults or left out. In my opinion, extra optimization flags should not leave make.conf. Vendor doesn't test those, so having in port adds to maintenance to check with clang/gcc or on different release/architecture tuples.
