We ran into hang issues with libtool linking imagemagick in msys2, using
version based on 3.5.5, 3 times in a row on our ARM64 runner.  We applied
your v2 patch to our 3.5.5 branch (with the change of current_sig to sig),
and the issue no longer occurred.  (I also tested with the existing 3.5.4
version, and it didn't hang either).

Note that kill -CHLD to either the child sh.exe or the parent make.exe did
not unblock things, but killing sh.exe (SIGTERM) did cause the make to
fail as expected.
