The spec files can be changed by hand after you have built the compiler.

Take a look at the info pages for gcc . Search for Spec files.

Lets say you want to add a startfile depending on a command line option 
you would do something like :

%startfile: {option: includeifoptionchosen.o%s} {!option:normal 
startfileslist}

or just add this as a condition in your specs.(btw the %s is if you want 
 the compiler driver to search for the files in the system specs.)
