grep 2.5 install failure

[Karl Berry]

Grep 2.5 failed to install cleanly:

      /usr/local/gnu/bin/install -c grep /usr/local/gnu/bin/grep
    ln -s grep /usr/local/gnu/bin/egrep
    ln: `/usr/local/gnu/bin/egrep': File exists
    make[2]: *** [install-exec-local] Error 1

I believe the Makefile should rm -f $(bindir)/egrep $(bindir)/fgrep 
before attempting to create them as a symlink.

Thanks,
karl
