You can't produce a pre-compiled machine code binary of your guile
program.  I believe you can use the environment variable
GUILE_JIT_THRESHOLD set to zero to have your code compiled to
machine code on first use.

$ GUILE_JIT_THRESHOLD=0 guile my-program.scm

You can also start execution of your guile program from C using
the techniques described in the section "Programming in C" in the
Guile Reference Manual.
