`AArch64` GCCs exit with an error condition when they encounter any kind of floating point code if the `nofp` and/or `nosimd` compiler flags have been set. Therefore, evaluate if those flags are present and set a boolean that causes any compiler-rt intrinsics that contain floating point source to be excluded for this target. This patch prepares rust-lang/rust#68334
