After fixing (or working around?) #1142193 with the patch that I
attached there, when I try to build vkd3d in an armhf chroot on the
arm64 porterbox amdahl, most of the test suite segfaults. See attached
test-suite.log.

When I tried to get a backtrace using gdb, I got multiple of these
warnings, which might be relevant:

% p=$(basename "$(pwd)"); d=; a=armhf; s="smcv${p:+"-$p"}${d:+"-$d"}${a:+"-$a"}"; schroot -c "$s" -r -- libtool --mode=execute linux32 gdb ./tests/hlsl_d3d12
...
warning: JITed object file architecture armv8-a is not compatible with target architecture armv7.

I don't know whether this failure mode would also occur on buildds, and
I don't think out-of-archive mechanisms like Salsa-CI and debusine offer
an armhf environment.

Wine upstream no longer supports 32-bit ARM, and nothing in Debian seems
to depend on vkd3d anyway, so I think it might be most realistic to drop
vkd3d from the armhf architecture and then ask the ftp team to remove
the old "cruft" binaries, rather than chasing after a solution to this.

I was able to get this backtrace, which seems like the issue might be in
generated code (?) in Mesa, rather than vkd3d, if it helps:

smcv@amdahl ~/vkd3d % p=$(basename "$(pwd)"); d=; a=armhf; s="smcv${p:+"-$p"}${d:+"-$d"}${a:+"-$a"}"; schroot -c "$s" -r -- libtool --mode=execute env DEBUGINFOD_URLS=https://debuginfod.debian.net linux32 gdb ./tests/hlsl_d3d12
