Making distclean

[Martin von Loewis]

After reading the INSTALL stuff in 1.0 (which is really good), I decided
to have my own objdir, unlike having objdir==srcdir, as I did in the past.

First, configure said it won't work as there is a configuration in
srcdir. So I made distclean, and then it seemed to work ...

... until it tried to make g77.c. This is usally made as a symlink
from gcc.c. Since the link was already in the source directory, the
VPATH found it. The next compilation step expected g77.c in the source
directory, so compilation failed.

I think make distclean should also remove the symbolic links that might
have been made.
