I see a strange error when I attempt to configure perl on a NetBSD 9.3
server :

.
.
.
If this doesn't make any sense to you, just accept the default 'n'.
Build a threading Perl? [n]
Your platform has some specific hints regarding threaded builds, using
them...

Perl can be built so that multiple Perl interpreters can coexist
within the same Perl executable.

If this doesn't make any sense to you, just accept the default 'n'.
Build Perl for multiplicity? [n]

Use which C compiler? [cc] gcc
gcc: error: unrecognized command line option ‘--whole-archive’; did you
mean ‘--whole-program’?

Hmm... Looks kind of like a BSD system, but we'll see...

.
.
.

I have never seen that before.

Perhaps there is some strange compiler test in the config script?

For the record this is NetBSD 9.3 on sparcv9 :

There's a test done in the compiler callback unit to test where the
compiler supports that flag. It looks like it needs an extra
redirection to prevent the noise.

The "--whole-archive" option was needed in very old NetBSD, though
no-one involved (including myself, who added the CBU) added a ticket
reference.

Looks trivial to fix and I am working on it. The compile is running
now and I will report back when I have a clean testsuite.

OKay I seem to have exocised the demons.

A few trivial edits later and we get a clean compile :
