[Buildroot] [PATCH 1/2] package/samba4: fix build on m68k

[Buildroot] [PATCH 1/2] package/samba4: fix build on m68k

[Bernd Kuhls]

samba4 uses very big switch statements, which causes the build to fail
on m68k, because the offsets there are only 16-bit.

We fix that by using -mlong-jump-table-offsets on m68k to use 32-bit
offsets for switch statements, but this is only available starting with
gcc 7 [0] [1].

Only one package selects samba4, mpd, but it already depends on gcc
>= 12. As such, we do not need to propagate that new dependency.

Fixes:
