wrk under aarch64 (ARM64) fails

[tobbik]

Running wrk on an ARM-64 platform(ASUS C101) gives bus error
The error could be reproduced on a Raspberry pi4 under ArchLinuxARM64. It is descriped upstream and has an existing pull request upstream: wg/wrk@e2ab808

Steps to reproduce
Run wrk on a ARM-64 hardware against a known server. On my C101 wrk -t 4 -c 10 -d 5 http://www.google.com fails repeatedly.

Expected behavior
It should run without the bus error.

Additional information
I used below patch (copied from the pull request) and compiled it on ARM-64, ARM-32 and x86-64 and it worked without problems. it wouldn't allow to add this patch as attachement so I c'np it here

Should be fixed in 4.1.0-2. Try pkg upgrade.

Thank you, confirmed to work on ASUS C101 (armv8l).
