Mats Kindahl c6d64e3e8d Fix compile issues in prerelease tests
There are some flags that cannot be used in preprelease tests, which
this commit fixes. It uses the flag `-DWARNINGS_AS_ERRORS=OFF` to not
turn warnings into errors for release builds. In addition, explicit
checks for compiler flags are added instead of using a function, which
for some reason causes problems.

Note that the prerelease tests run on a regular schedule as well.
