[Bug 278630] math/kamis, misc/openn: GCC fails with an error on armv7: use of built-in trait '__remove_cvref(_InIter1)' in function signature; use library traits instead

Hmm:

[00:00:26] Ignoring   math/kamis | kamis-3.1: is marked as broken: requires
OpenMP support that is missing on this architecture

Looking at the Makefile: no use of gcc with libc++ use is set up for there as
well.

The submittal gives no clue how it was set up to test with gcc.

So I had to hack things to test math/kamis .

. . . Result:

does not.
