[bug-gawk] macOS: mpfrsqrt check fails on gawk-4.2-stable and master branches

[Hermann Peifer]

Hi aiagin,

Below is what I am getting on my MacBook, now that all MPFR tests are
executed by make check. There is no error when switching to branch
gawk-4.1-stable and running make check there, i.e. using: GNU Awk 4.1.4,
API: 1.1 (GNU MPFR 3.1.6, GNU MP 6.1.2)

$ ./bootstrap.sh && ./configure && make && make check
...

make[2]: *** [Makefile:4633: pass-fail] Error 1
