...and you don't happen to have 1) an IBM Z machine 2) a PowerPC/Power ISA box with at least one LPAR running AIX (or ppc/ppc64 Linux, if there are any distributions left not doing ppcle/ppc64le) or 3) a SPARC box next to your desk, running an emulated s390x (or possibly emulated big-endian PPC/Power ISA or SPARC) on a sufficiently fast host and with a reasonable amount of emulated memory isn't *too* painful.
A Wireshark build ain't fast - the fastest I got with a recent fully-loaded M5 Max MacBook Pro on an emulated s390x with 4 cores and 8GB of emulated memory was, for a build from a freshly-created and CMaked build directory, was:
real 172m21.036s
user 537m59.375s
sys 110m18.051s
but it's better than a poke in the eye with a sharp stick. 16GB of emulated memory was faster, but not by much.
(I didn't experiment with the JIT cache size; a bigger JIT cache *might* help, especially if the JIT cache uses physical addresses and the machine has enough memory to keep all the passes of the oompiler in memrory, so the translated compiler code also remains resident.)
