      The GDB disassembler does not support APX.

      Reproducer:

      cat >apx.s <<EOF
	.text
f:
	push2 %rax, %rbx
EOF
as apx.s
gdb -quiet -ex "disassemble f" -ex quit a.out

      Current output:

      Reading symbols from a.out...
(No debugging symbols found in a.out)
Dump of assembler code for function f:
   0x0000000000000000 <+0>:	(bad)
   0x0000000000000001 <+1>:	hlt
   0x0000000000000002 <+2>:	fs sbb %bh,%bh
   0x0000000000000005 <+5>:	lock
End of assembler dump.

      Expected output: Something similar to what objdump prints:

      0000000000000000 <f>:
   0:	62 f4 64 18 ff f0    	push2  %rax,%rbx

      Seen with: gdb-14.1-8.el10.x86_64
