No problem.

I think it was used for the _default_ extension a compiler produces.

Yes, all you need to do is change the second line to
  program_elf_SOURCES = main.c

Just remember a bunch of characters need to be mapped to '_' for the
variable naming, because otherwise `make' would give syntax errors, for
example (the content of Makefile.am ends up in Makefile).

Also note on some systems/compilers, your program will have another
extension.  E.g., it may end up as program.elf.exe.
Surely the name doesn't suggest that you'll actually target w32..  ;)

Cheers,
