lang/intel-compute-runtime 20.30.17454 build failure -> 20.32.17625 also fails

[José Pérez]

Hi,
I have two successfull builds now. One with 12.1-STABLE on AMD
processor and a second one on a CURRENT kernel with a previously
failing processor.

I am to assume this was a bug fixed in CURRENT, so I won't investigate
further.

AFAIK an AMD should be able to emit correct Intel code, even if it does 
not run it.

In theory it should be possible to cross compile from, say, an ARM, no?

Yes, see second CPU above.

All failed on CPU 1.

Thank you for your suggestions.
