subdir builds & $objdir/$output_objdir

[Bob Friesenhahn]

In my opinion, libtool 2.0 should not be released unless it is capable 
of building libraries in subdirectories.  Currently, the rules for a 
number of compilers/systems use $objdir or $output_objdir as part of 
the rule.  This causes build failure since $objdir and $output_objdir 
are just ".libs" and the .libs subdirectory does not exist.

For example, under Digital Unix (OSF), this fragment is generated (and 
fails):

  -update_registry .libs/so_locations -o 
Magick++/lib/.libs/libGraphicsMagick++.so.2.0.0

This is due to use of

  -update_registry \${objdir}/so_locations -o \$lib

in the archive_expsym_cmds rule.

The failure under IRIX is similar except that $output_objdir is used 
to refer to the .libs sub-directory (with similar results).

If there is a replacement variable which refers to the actual object 
target directory, then it may be used to replace 
$objdir/$output_objdir in the linkage rules.  Or perhaps, the 
definition of $output_objdir can be fixed, and it can be used 
consistently in rules which refer to the .libs directory.
