  CMake: demote failure to compile IEEE 754 test from error to warning

Apparently due to a CMake bug, some (but not all) CMake versions attempt to
compile the test with default flags, which means C++98 mode with GCC < 6.
As a result, compiling the test fails, and the whole game fails to build.

@gfgtdf pointed out to me that CMake reports the compile and run status
separately, and therefore it's possible to detect the situation where the
test fails to compile. Thus, I decided to allow building in that situation.
