* src/Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
It has nothing to do with building Emacs, and no-one is likely to be
paying attention to the result. The CANNOT_DUMP branch was pointless,
since it sets EMACSLOADPATH=$(lispsource) it is impossible for there
to ever be any shadows. The EMACSLOADPATH setting was probably necessary
for emacs to work at all when uninstalled, given the way init_lread
works for the CANNOT_DUMP case. Since -batch implies -q, in the
non-CANNOT_DUMP branch, any shadows could only come from site-lisp
files.
