Compile for Android issue

[Emmanuel Maillard]

Hi,

I try to cross-compile gnustep-base-1.24.0 for Android.
I already have fix some issues (patches will come soon), I checked Makefiles 
but I didn't find how to fix this target issue.
(used makefiles are gnustep-make-2.6.2)

<snip>…</snip>
 Compiling file NSMessagePortNameServer.m ...
 Compiling file GSFFIInvocation.m ...
make[4]: *** No rule to make target `Additions/obj/subproject.o', needed by 
`obj/libgnustep-base.a'.  Stop.
make[3]: *** [internal-library-all_] Error 2
make[2]: *** [libgnustep-base.all.library.variables] Error 2
make[1]: *** [internal-all] Error 2
make: *** [internal-all] Error 2

Any help is welcome.

Thanks
Emmanuel
