Issue:
Cross-compiled `bitcoind -signet` silently fails on Windows
The issue was [discovered](https://github.com/bitcoin/bitcoin/issues/24501#issuecomment-1079738588) during 23.0rc2 testing.

MSVC build works flawlessly.

`bitcoind -testnet` also works flawlessly.


Discussion / hints:
22.0 also works fine?
I (assume) I've reproduced this, running the rc2 binaries under wine. Took a number of start / restarts:
```bash
wine bitcoin-23.0rc2/bin/bitcoind.exe -signet -debug

> 22.0 also works fine?

Yes. Just tested.
I think I got the same issue  (but for `bitcoin-qt.exe` on Windows 10 Home / Version 20H2 on VMWare).

It was installed using [bitcoin-23.0rc2-win64-setup.exe](https://bitcoincore.org/bin/bitcoin-core-23.0/test.rc2/bitcoin-23.0rc2-win64-setup.exe)

The application abruptly quits and no messages are logged in `debug.log`. The last lines are about `UpdateTip: new best=00000000...`.
Initially I thought it was a problem related to the virtualization resources, but then I noticed that the same doesn't happen for version 22.



FWIW, we've managed to trace at least @fanquake's crash to the avx2 implementation of sha256sum:
```
$ addr2line -e bin/bitcoin.exe.dbg -aipfC 0x14051cc65
0x000000014051cc65: sha256d64_avx2::Transform_8way(unsigned char*, unsigned char const*) at /distsrc-base/distsrc-23.0rc2-x86_64-w64-mingw32/src/crypto/sha256_avx2.cpp:316
```
This probably explains why I couldn't reproduce it in wine. The computer I was using doesn't have either instruction set.

According to @sipa you might need a AVX2 capable CPU which doesn't support SHA-NI to get this code path.

It could be a compiler bug around AVX2 intrinsics or something.
It's probably: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54412

The stack is 16 byte aligned according to the ABI, but gcc assumes 32 byte alignment during register spilling (doesn't re-align the stack pointer), resulting in ~50% chance of a crash.

Looks like we'll have to disable AVX2 (anything that uses 256 bit types) on mingw builds. Probably least impact to disable it in during detection in `configure.ac`.
