Avoid checking for arm/aarch64 in toolchain path

[georges-arm]

Since the CMAKE_CXX_COMPILER contains the full path including directory components, this check will enable Arm intrinsics even on non-Arm platforms if the directory the compiler resides in happens to contain the substring "arm", for example:

    /home/parma/toolchains/g++-14
           ^^^

CMAKE_SYSTEM_PROCESSOR already specifies the target architecture so there is no need to additionally check the compiler string, therefore we simply remove this condition.

LOL, good one.

Thanks for the fix, we'll have a look and probably merge soon.

Oh, thanks. Good catch.
I think we'll merge this for now, but internally I completely reworked the architecture detection heuristics. So with the next update on Github your fix will be overwritten.

Have you tried building VVdeC with your setup? Did that work? In VVdeC the heuristics are already as they will be in VVenC after the next update. Some feedback would be nice.

Thanks for the quick review!

I just had a quick try and VVdeC seems to work fine on both x86_64 and AArch64 as well as for cross compiling. 👍
