poudriere itself - yes, ports building - no (see BUILD_AS_NON_ROOT).

Neither do I. poudriere can also be used interactively e.g.,

  $ poudriere testport -ij 111aarch64 lang/ocaml.

if you want to investigate more and don't have a ready fix yet.

poudriere can use qemu-user (at least on i386 and amd64) to emulate
aarch64, armv6, armv7, mips, mips64. However, emulation is slow thus
native-xtools are used to speed up the build via statically-linked host
binaries[1] for target architecture under /nxb-bin prepended in PATH.

EuroBSDCon 2014 had some presentations about this by sbruno and bapt:
