It isn't just a compilation problem, it really can't work at all.
Without the patch, if the function builds, it looks like:
00000000002308b0 <_gfortran_kill>:
2308b0: f3 0f 1e fa endbr64
2308b4: 48 83 ec 08 sub $0x8,%rsp
2308b8: e8 f3 ff ff ff callq 2308b0 <_gfortran_kill>
2308bd: 85 c0 test %eax,%eax
2308bf: 74 07 je 2308c8 <_gfortran_kill+0x18>
2308c1: e8 4a 92 de ff callq 19b10 <__errno_location@plt>
2308c6: 8b 00 mov (%rax),%eax
2308c8: 48 83 c4 08 add $0x8,%rsp
2308cc: c3 retq
2308cd: 0f 1f 00 nopl (%rax)
i.e. there is endless recursion, it doesn't call the libc kill, but itself.
