The problem appears to be that _freeze_importlib is a binary compiled and
ran at build time but using the target compiler.  For you your build
environment and the target environment were probably close enough that it
works, on some ABs the loader paths are different, and obviously if you
build for a different architecture it just fails.

| ./Programs/_freeze_importlib: 1: ./Programs/_freeze_importlib: Syntax
error: word unexpected (expecting ")")

$ file _freeze_importlib
_freeze_importlib: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux.so.3, for GNU/Linux 2.6.32,
BuildID[sha1]=f5defa61a5f1e65c6be7219dc1bfff59d510cd78, not stripped

Yeah running an ARM binary on x86 isn't going to work.
