d9080f5d3a Check linking of hardening options, give better warnings if it fails. 
Previously we'd only check whether the hardening options succeeded
at the compile step. Now we'll try to link with them too, and tell
the user in advance if something seems likely to go wrong.

Closes ticket 18895.

for another case.

e57f26c135 Have correct_tm set tm_wday as well. 
The tm_wday field had been left uninitialized, which was causing
some assertions to fail on Windows unit tests.

Fixes bug 18977.

ce854a8d22 Add -ftrapv to gcc-hardening ... mostly! 
We know there are overflows in curve25519-donna-c32, so we'll have
to have that one be fwrapv.

Only apply the asan, ubsan, and trapv options to the code that does
not need to run in constant time.  Those options introduce branches
to the code they instrument.

(These introduced branches should never actually be taken, so it
might _still_ be constant time after all, but branch predictors are
complicated enough that I'm not really confident here. Let's aim for
safety.)

Closes 17983.
