OK, unless a build maintainer has objections.

Thanks for your patch and to Dave, who confirmed in the PR
that the patch works on HPUX.

PS: I had used GCC_TRY_COMPILE_OR_LINK rather than AC_TRY_LINK
to increase the chance that it works with bare-iron targets, but
probably gfortran is not build on those and besides cache override
works. (Additionally, it is not the only link test.)
