libobjc2 not detected by GNUstep Make when installed in /usr/local

[Quentin Mathé]

Hi,

libobjc2 is now compiled with a normal Makefile (a GNUmakefile was used 
previously and the Makefile was provided as an extra option, so I never tried 
the Makefile).
As a result, the library gets installed in /usr/local, but GNUstep Make is 
unable to detect this custom libobjc (at least when CC is GCC 4.4). I looked at 
the config.log and gs_cv_objc_libdir and gs_cv_objc_incdir are both set to 
NONE. 

I worked around the problem by creating symbolic links in 
System/Library/Headers and System/Library/Libraries which point back to the 
libobjc installed in /usr/local.
It's quite possible I have done something wrong… If it isn't the case, it would 
be nice if such a custom libobjc2 install could be handled transparently.

Cheers,
Quentin.
