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

peff · gitster · commit ddbc8a6d3e15 · 2017-07-10T10:02:30.000-07:00
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).
