[patch 34/39] find out ilasm for cross compiling

Currently, pnet unconditionally tries to run the self-built ilasm. If we
are crosscompiling, ilasm was built for the "host" system, so we cannot
run it on the "build" box.

This patch checks if we find ilasm in the $PATH, so while cross
compiling, just make sure that an ilasm tool built for the "build"
platform is available there.
