As a test, I've used qemu under FreeBSD/amd64 to build two packages for MIPS32:
pkg-1.6.1.txz and mpd-5.7_3.txz and stored them to USB flash.

I've mounted that USB flash as /usr/local in my TL WDR3600, extracted pkg-static
and tried to install both packages and got kernel panic in process:

# ./pkg-static install -yU /usr/local/pkg/*.txz
pkg-static: Repository FreeBSD cannot be opened. 'pkg update' required
Checking integrity... done (0 conflicting)
The following 2 package(s) will be affected (of 0 checked):

New packages to be INSTALLED:
        mpd5: 5.7_3
        pkg: 1.6.1

The process will require 12 MiB more space.

This is repeatable. This time the device used system built using HEAD sources r289362
with MALLOC_PRODUCTION.
