 Ok, the solution was for a wrong problem... but a problem anyway when doing
Canadian Cross...

 In embedding we don't need the 'objective-c' language at all and the Cygnus 
patches have removed almost all references to it, but leaved this (a bug). So
simply remove the 'objective-c' from the prerequisities of 'native'. There is
a line starting with 'native:' in your Makefile and after it a list of things
to do earlier, before going to make 'native'. If the 'objective-c' target has
been removed, there are no rule how to do it...

 I looked my gcc-2.8.1 sources and found that you the 'objective-c' is probably 
included in the 'LANGUAGES' definition, so it isn't straightly in the 'native:'
line.

 Yes, just my lousy memory...

 Ok, the fix wasn't quite useful for this bug...

 The 'cc1obj' is the Objective-C compiler, 'cc1plus' the C++ compiler
to be made.  The Objective-C isn't needed, and the crossgcc-patches
tried to remove all references to it but failed... There are one or
more extra 'objective-c' references left to remove...
