With this CFLAGS setting, my 12.1 and 13.1 builds pass make check.

Should we add autoconf foo to prevent Intel from shooting the user in the foot?

Agreed.  Think that's worth a ticket?  In my work I tend to gather
fast-math safe logic into one convenience library, no-fast-math into
another convenience library, and then create the installed .so from
those two outputs.  This permits using -fsomething-sane only where
necessary.
