getconf: LONG_BIT: unknown variable

[mndrix]

On OpenBSD 7.5 amd64 running opam version 2.3.0~alpha1, opam upgrade produces the following error:

getconf: LONG_BIT: unknown variable
'opam upgrade' failed.
Fatal error:
End_of_file

The output of opam config report 2>&1 encounters the same error:

# opam config report
# opam-version         2.3.0~alpha1
# self-upgrade         no
getconf: LONG_BIT: unknown variable
# read-state           End_of_file

It doesn't look like I'll get around to sending a patch this week, but maybe this weekend 🤞

Cross-referencing #5950

It looks like OpenBSD is the only unix platform i could find where uname -m actually returns the "kernel architecture" instead of the "machine architecture" so the call to getconf LONG_BIT or equivalent is not required here.

Source:

• https://man.openbsd.org/uname.1 (tested in qemu)
• https://man.netbsd.org/uname.1
• https://man.freebsd.org/cgi/man.cgi?query=uname
• https://man.dragonflybsd.org/?command=uname&section=1

I'll open a PR in the next hour

That took a bit longer than expected as i had an idea on how to improve related code and discovered a bug elsewhere.
Anyway, this hasn't been tested outside of Linux yet but i believe it should work so feel free to test it: #6217

Confirming that #6217 fixes this problem for me
