share/mk/bsd.host.mk has

# disable compiler options that interfere with dtrace
HOST_DTRACE_OPTS?=	-fno-omit-frame-pointer -fno-optimize-sibling-calls -fno-ipa-sra

which should probably be conditionalized depending on what the host
compiler is, but it doesn't look like we have the infrastructure in
place.

For now you can just override it in your local build.
