I just forget most important, use `--optarch=mAVX2` (or similar) switch
for easybuild (or set the corresponding environmental variable)

Dear Mikaael,
That's a bug in intel/2018a. Unfortunately, you should use the right
-m option (for example -mAVX2)
Sincerely,

Sorry if this is a bit off-topic;
Since EasyBuild uses -xHost or equivalent, intel puts some
cpu-feature-indicator checks into all programs.
For even the simplest program (even a trivial "int main() {return
0;}"), when trying to run on AMD EPYC i get;
Please verify that both the operating system and the processor
support Intel(R) X87, CMOV, MMX, FXSAVE, SSE, SSE2, SSE3, SSSE3,
SSE4_1, SSE4_2, MOVBE, POPCNT, F16C, AVX, FMA, BMI, LZCNT and AVX2
instructions.
We only have a single EPYC machine that we bought for testing, and I
was hoping to let all users on our cluster try it out. But, pretty
much all software from the intel tree is not inaccessible, even
though I think most of them don't have any unsupported op-codes
(though I might be wrong).
Anyone know of any work-around to force ignoring this error, or am I
simply stuck with the foss-tree (which seems to work fine), as we
won't be rebuilding the entire tree just for a bit of testing.
Best regards, Mikael
