Besides, consider what if ccache decided to take the same policy: all
of a sudden, it would stop finding distcc (if it's a gcc->distcc link)
and going straight to gcc (assuming that's not also a symlink in say
~/bin).

IMHO the right way to do it is to search for argv[0] in the PATH, drop
everything you find until you encounter yourself, and start searching
for another occurrence of argv[0] starting from there.  The tricky
part is to tell when you've encountered yourself, though.
