Make sure there is a value you do know. For example, write a module
containing just a big string. Require that it is always included in
any executable supported by your system. Compute its CRC. Now you
have a starting-point for searching.

No solution will be completely cross-platform; different platforms
have different executable formats. But if you support say ELF and PE
(COFF), you'll cover a lot of platforms...
