Thanks, applied (with one tweak) as r24334.

You're probably better off not knowing. Let's just say:
1) probe your system for configuration information
2) generate a Makefile from a template
3) pass part of that generated Makefile to the program which generates
pbc_to_exe.pir from a template
4) as part of that process, pass the Makefile snippet to a program which
generates a compiler command
5) write pbc_to_exe.pir to a PBC file
6) run the PBC file through itself, which:
6a) converts PBC to a static array in the source code of a C program
6b) compiles that C program using the compilation instructions generated in #4
Making it work on PIR files, not just PBC files, is almost trivial in
comparison.
