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
3e48f8358e519f9c24262a6549d8f6c78ee01add:

In file included from fp.c:6:
fp-gnum68k.c:21:10: fatal error: fpu_control.h: No such file or directory
   21 | #include <fpu_control.h>
      |          ^~~~~~~~~~~~~~~

Add also upstream link to first patch iteration which was sent in
