I was able to run the pkg-static in the background and attach gdb
to it in the chroot:

I had previously done:

pkg-static del FreeBSD-set-base FreeBSD-set-base-dbg FreeBSD-set-devel FreeBSD-set-devel-dbg FreeBSD-set-minimal FreeBSD-set-minimal-dbg FreeBSD-set-kernels FreeBSD-set-kernels-dbg

( FreeBSD-set-lib32* are missing only because this is an armv7 context that can not have such. )
