After an update, boinccmd and boincmgr crash with "Illegal instruction"..?!

Log:
kernel: traps: boinccmd[1250032] trap invalid opcode ip:7fa11f98453c
sp:7ffd25f42c40 error:0 in libboinc.so.7.18.1[7fa11f968000+52000]
kernel: traps: boincmgr[1251274] trap invalid opcode ip:55814c1a6689
sp:7ffe16eb6840 error:0 in boincmgr[55814c17d000+18e000]

Still happily crunching; boinctui still works for suspend/resume.

Sorry for the oversight, it was the old client binary still running..
A boinc-client.service restart also fails with:

kernel: traps: boinc[1263003] trap invalid opcode ip:562370352cf4 sp:7ffedd7ca2c0 error:0 in boinc[56237034a000+c0000]
systemd[1]: boinc-client.service: Failed with result 'signal'.

Downgraded to 7.16.16+dfsg-1, which works but now spams the log with "No protocol specified" 😏

Dear Maintainer,
I could reproduce this issue inside a minimal QEMU VM
with a CPU lacking the AVX instructions.

It looks like the patch new-autoconf-build-fix.patch introduced
adding of "-mavx" to CXXFLAGS flags.

Salsa already contains a patch [1] to remove that "-mavx":
   "Reversing -mavx for compatibility with older servers"

A package version containing this patch is not yet released.

Kind regards,
Bernhard
