building "security/sudo" on evbmips64-el?

Recalling these threads:

  http://mail-index.netbsd.org/port-evbmips/2016/09/09/msg000284.html
  http://mail-index.netbsd.org/port-evbmips/2016/09/11/msg000289.html

The test case in the second thread still fails (and is worked around)
the same now as then.

During the configure phase of "security/sudo", the following is printed:

  checking whether the linker accepts -Wl,-z,relro... no

leading me to try building without taking any special measures.

Then, however, I run into the following infinite loop:

[...]

I normally have MAKE_JOBS set to "ncpu+1" (2 in this case).  Forcing it
back to 1 for "sudo", I end up with a similar predicament:

[...]

What's going on here?  I've so-far built:

cwrappers-20170112
pkg_chk-2.0.8
pkg_tarup-1.9.1
pkg_rolling-replace-0.24.2
digest-20160304
perl-5.24.1
lintpkgsrc-4.92nb1
m4-1.4.17
libtool-base-2.4.6
bsdtar-3.3.1
gmake-4.1nb3
pkgconf-1.0.1
osabi-NetBSD-7.99.67
x11-links-1.05
fluxbox-1.3.7

on this system (Lemote YeeLoong) and not had any trouble so far.
(modulo the "soft-float" issue with "cwrappers").

In case it matters, I'm building entirely on local FFSv2 filesystem,
albeit via a USB->SATA adapter.  The pkgsrc tree is on NFS.
