libtool-1.5.22, please hold a little

[Peter O'Gorman]

Hi,
I'd like to fix this before 1.5.22:

peter$ ./libtool --mode=link --tag=CC gcc -o libfoo.la foo.lo -rpath /nono 
-L../nothere
./libtool: line 1: cd: ../nothere: No such file or directory
libtool: link: cannot determine absolute directory name of `../nothere'

IMO, it should just keep any relative directory -L paths as is if they don't 
exist.

Peter
