build: Add a way to set CFLAGS for AddressSanitizer etc.
We don't want to set these globally via the normal CFLAGS, because if
we did, AddressSanitizer would catch test-segfault deliberately
segfaulting, and "helpfully" turn it into exit status 1, which in turn
makes our test fail because it asserts that the segfault is reported
as a segfault.
A typical use with gcc as compiler, on a reasonably recent Debian,
would be:
./configure SANITIZE_CFLAGS="-fsanitize=address -fsanitize=undefined -fPIE -pie"
