subdir-build tests?

[Bob Friesenhahn]

The old development libtool I am using to support GraphicsMagick is 
proving to be broken for sources & lib in subdirectory & VPATH builds 
of C++ code when the compiler is not GCC.  There is a failure at 
link-time which is similar with two compilers (IRIX and Digital Unix). 
I don't see anything in libtool's current test suite which would test 
this.  Without a test, libtool is most likely still broken.

In this case we have

/path/to/find/sources
path/to/put/objects
path/to/put/lib

Here are sample link-time errors:

IRIX:

ld32: ERROR   48 : Cannot access registry file .libs/so_locations (No such file 
or directory) - ignored.
ld32: INFO    152: Output file removed because of error.

Digital Unix (Compaq/Hp):

ld (prelink):
Cannot open file .libs/so_locations to write
ld:
Cannot open file .libs/so_locations to write

Note that in this case, libtool has been requested to link to a 
library with path Magick++/lib/libGraphicsMagick++.la but it is 
referring to .libs in the current directory (which does not exist).
