Not sure to really understand:
picking up libobjc2, not libobjc2
...
I suppose you're referencing those two lines:

checking for custom shared objc library... NONE
checking for the flag to link libobjc... -lobjc

Anyway there's definitively NO gobjc installed here!

Plus,
- the "OBJCFLAGS=-I/usr/local/include" option in my command line point 
to the correct location of the OBJC headers needed,
- thus, issuing:
echo $LD_LIBRARY_PATH
I got
/home/ylg/GNUstep/Library/Libraries:/usr/GNUstep/Local/Library/Libraries:/usr/GNUstep/System/Library/Libraries:/usr/local/lib

Since I manually added both the variable and its content, and still 
referencing Richard's remark about the 'virtual exixtence' of ~/GNUstep 
directory, I do not really care of it doesn't exist yet. But I really 
care about the whole endof this late output:
It actually point to a location that DID NOT EXIST!?

Recapitulation
Very FRESH Debian Install
GCC is 4.9 and 5.x are installed by default with the buildessential.deb)
the necessary libs to perform a GNUstep complete build (libffi-dev, 
libxml2-dev, libicu-dev, libgmp3-dev, libssl-dev, libxslt-dev, 
libjpeg-dev, libtiff-dev, libpng-dev, libcairo-dev, libxt-dev, 
libgl1-mesa-dev, libglu1-mesa-dev, libgnutls-dev, liblcms1-dev, libical-dev)
clang/llvm 3.7 (installed from lvm.org/APT packges)
libobjc2 (build from sources as previously explain, all successfully ran 
tests).

--Seems corect isnt' it?

6 - OK, lets run couple more commands:
a) echo $LD_LIBRARY_PATH
/home/ylg/GNUstep/Library/Libraries:/usr/GNUstep/Local/Library/Libraries:/usr/GNUstep/System/Library/Libraries:/usr/local/lib

WRONG! Everething on this line are WRONG!

b) ls /usr/GNUstep/
System

As one may read, my newly created /usr/GNUstep/ dir doesn't contain any 
Local dir that in its turn, obviously can't contain anything indeed.

Also, as one may have notice that in my 3, I lately have introduce the 
LD_LIBRARY_PATH in the command line...
So why at the end of the Make building, this PATH has been modified the 
wrong way since nothing describe here doesn't exist in my system?

Still I really hope that's nobody's fault but mine but of course I can't 
see where I'm wrong 'till now...!!!???

later,
