openssh: Add a work around for ICE on mips/mips64

Browse Source 
Unfortunately the new openssh version has an ICE on mips. This looks similar to:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104817
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104820

Given how long these have been open, workaround the issue by disabling the compiler
hardening options on mips.

It is likely better to do this than have the open CVEs for everyone
as we can't upgrade.

An example:

| during RTL pass: zero_call_used_regs
| clientloop.c: In function 'client_loop':
| clientloop.c:1699:1: internal compiler error: in int_mode_for_mode, at stor-layout.cc:407
|  1699 | }
|       | ^
| 0x14d0acc internal_error(char const*, ...)
| 	???:0
| 0x5cf765 fancy_abort(char const*, int, char const*)
| 	???:0
| 0x826f1f emit_move_insn_1(rtx_def*, rtx_def*)
| 	???:0
| 0x8270c5 emit_move_insn(rtx_def*, rtx_def*)
| 	???:0
| 0xb7b994 default_zero_call_used_regs(HARD_REG_SET)
| 	???:0
| Please submit a full bug report, with preprocessed source (by using -freport-bug).
| Please include the complete backtrace with any bug report.
