[Buildroot] [PATCH 4/4] toolchain-external: remove older Microblaze toolchain

[Jan Viktorin <xvikto03@stud.fit.vutbr.cz>]

Hello,

there is an issue with the newer toolchain I'm not able to solve. I tried to
google for a solution but I failed.

hidden symbol `__udivsi3' in buildroot/output/host/opt/ext-toolchain/bin/../lib/
gcc/microblazeel-unknown-linux-gnu/4.6.2/libgcc.a(udivsi3.o) is referenced by DSO

With the older one, it is possible to set `LD_PRELOAD=/lib/libgcc_s.so.1` to
solve (well, it is a hack...) that problem because it occurs during runtime.
With the 14.3 toolchain, it occurs earlier - during compilation.

Does anybody know how to solve that?

Would it be possible to not delete the older toolchain? I think it is possible
to do `git clone` and then just copy the archive to its place like this:

$ git clone https://github.com/Xilinx/microblaze_v2.0_le.git
Initialized empty Git repository in /home/user/microblaze_v2.0_le/.git/
remote: Counting objects: 4, done.
remote: Compressing objects: 100% (4/4), done.
remote: Total 4 (delta 0), reused 4 (delta 0)
Unpacking objects: 100% (4/4), done.
$ cp microblaze_v2.0_le/microblazeel-unknown-linux-gnu.tgz SOMEWHERE
$ rm -Rf microblaze_v2.0_le/

Well, I don't know how to integrate this method with Buildroot and I guess it
is probably the only reason to remove it, isn't it?

Regards
Jan Viktorin
