If you're cross compiling, yes.  It's not like this takes a huge
amount of time to figure out: You cross-compile schroedinger, it fails,
you realize that it attempts to use /some/prefix/orcc.exe, realize that
you need to a) get an orcc tool that runs locally, and b) tell schroedinger
to run that tool.  30 seconds looking in the Makefile tells you that
it's using the ORCC variable, which leads you directly to the solution
of using 'make ORCC=/usr/bin/orcc'.

If you overthink it, you might wonder if orcc has some platform
dependency, but either examining or executing the generated code would
lead you to think "probably not".  And indeed, the answer is no.
