gdb broken on armhf

[Mate Kukri]

Trying to step through an armhf program in gdb throws the following internal error:

```
/build/gdb-U0UiMP/gdb-14.0.50.20230907/gdb/displaced-stepping.c:283: internal-error: copy_insn_closure_by_addr: Assertion `buffer.copy_insn_closure.get () != nullpt
r' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
