bug#8878: 24.0.50; ./configure: line 17305: test: =: unary operator expected

[Peter Dyballa]

Updated a few hours ago (revno: 104605). Reason is that  
gl_cv_func_lstat_dereferences_slashed_symlink on this line 17305

     if test $gl_cv_func_lstat_dereferences_slashed_symlink = no; then

is empty.

This looks like a gnulib bug (in lstat.m4) to me.

Thanks, fixed in gnulib as follows, with the fix propagated
