Subject: sim: add support for build-time ar & ranlib

This is needed when building for a target whose ar & ranlib are
incompatible with the current build system.  For example, building
for Windows on a Linux system.

Then manually import the automake rule for libigen.a, but tweak the
tool variables to use the FOR_BUILD variants.
