[patch] Fix for AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK

[Tim Van Holder]

When preparing the DJGPP package for 2.50, I noticed test 143
(AC_FUNC_STAT) failed.  Cause: it found conftest.sym.exe.

As it turns out, AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK uses
ln -s without considering DJGPP (where symlinks are currently only
supported for executables, resulting in a .exe file being created).

Two alternatives are provided; one knows about the possibility
of a .exe file appearing and handles it; the other uses $as_ln_s to
determine whether running ln -s makes sense in the first place.
Both replace the use of conftest.* with conf$$.*.

    * acfunctions.m4: (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK) Use
    ln -s in a portable manner.
