I am stuck at this step : building libobjc2.
These are the steps and things done :

I don’t know the exact cause of your failure, so David might want to
add valuable information here.
But afaik some parts of libobjc2 2.0 are built from assembler code. The
needed code for the armhf architecture does not exist yet. That
architecture is 32bit. If you try the 64bit variant (aarch64) it should
work afaik.
If you want to build libobjc2 on armhf you will have to use the older
version 1.9 of libobjc (which does not require clang >= 8, but works
with older versions of clang as well).
We have a script prepared for this which should install GNUstep by just
running it:
https://github.com/plaurent/gnustep-build/blob/master/raspbian-10-clang-7.0-runtime-1.9-ARM/GNUstep-buildon-raspbian10.sh
If you are going to use aarch64 this one should work as well:
https://github.com/plaurent/gnustep-build/blob/master/debian-10-clang-8.0/GNUstep-20-buildon-debian10.sh
I’d be glad if David could approve this is correct.
Also, it would be very nice if anybody would like to do the missing
libobjc2 assembler implementation for armhf. I think this is a common
use case as long as the default arch for Raspbian is 32 bit. Even though
this arch will be running out of support at some time in the future, of
course.
For anybody building libobjc2 on a Debian based platform: Please note
there are also some very recent Debian source packages. I have not yet
tried to build them, but I think that approach sounds very promising:
https://github.com/trunkmaster/nextspace/tree/master/Packaging/Debian
(this will only work if you try it on the supported platforms of
course).
Cheers
