Thomas Petazzoni a9a56ab6fd package/gdb: add support for GDB 14.1
All patches are still relevant, and have been rebased on top of GDB
14.1.

GDB 14.1 now needs mpfr unconditionally, so it is added as a
dependency of host-gdb, and of gdb when the full debugger is built.

[yann.morin.1998@free.fr:
  - add comment about selecting mpfr for 14.x or later
]

140 | for (i = 0; i < ELF_NFPREG - 1; i++, regbuf += flen)
| ^~~~~~~~~~
| ELF_NGREG
musl fixed the issue with
