bug#60731: configure does not check for space behind "-l"

[Karl Berry]

Hi Christian - thanks for the report.

        -L* | -R* | -l*)
           # Some compilers place space between "-{L,R}" and the path.
           # Remove the space.
           if test $p = "-L" ||
              test $p = "-R"; then

>From the case label, it seems clear that -l was intended to be
supported and simply missed from the if statement. 

However, this code is in libtool[.m4], not automake. Attempting to
reassign the bug there. I don't know if debbugs will send mail to the
new list, so explicitly cc-ing bug-libtool. (Hope we don't end up with
two bug numbers.) --best, karl.
