Subject: Makefile: turn off -fomit-frame-pointer with sanitizers
X-Git-Tag: v2.14.0-rc0~1^2~1

Makefile: turn off -fomit-frame-pointer with sanitizers

The ASan manual recommends disabling this optimization, as
it can make the backtraces produced by the tool harder to
follow (and since this is a test-debug build, we don't care
about squeezing out every last drop of performance).
