Set most compiler flags as late as possible in configure.
Some flags, e.g. -Wfatal-errors, will cause tests in configure to behave incorrectly so we have not been able to add them to --enable-test. Add the compiler flags as late as possible so configure checks are not affected. This will allow us to add flags that we need for testing without having to explicitly pass them to make.
