ltdl.c patch

[Steve Ellcey]

I noticed that it is possible to try and free "canonical" in
foreach_dirinpath even if it is never initialized, for instance if we go
into one of the initial ifs at the start of foreach_dirinpath that has a
"goto cleanup" in it.  This simple patch just initializes canonical to 0
so we don't try to free an undefined pointer.  It will result in us
trying to free a NULL pointer but LT_DLFREE seems to deal with that.

I have a copyright assignment on file but no write permssion to the
CVS tree.
