Looks like I never submitted it to bugzilla but my old
variant of the above was:

# svnlite diff sys/conf/kern.mk

In other words: I tried to span older clang's as well.
(Not that you should.)

You may want to process my bugzilla 215107 with head/sys/modules/zfs/Makefile
as it also deals with that -mminimal-toc: in other words to declare 215107
fixed by this update.
