Update patch to fix the following musl build failure with m68k which is
only raised (for an unknown reason) since bump to version 2.7.1 in commit

In file included from fp.c:6:
fp-gnum68k.c:21:10: fatal error: fpu_control.h: No such file or directory

Add also upstream link to first patch iteration which was sent in
November 2022 but didn't get it any reply (like most of the other emails
sent to bug-gsl@gnu.org ...)
