Thank you Stijn for taking care of this toolchain upgrade and Rosen for 
preparing it.

Did you compile umbim on MIPS 32 bit? I think I only saw the warning on 
such systems.

Did you create pull request for the packages which you fix?

Someone can later fix the rest of them. ;-)

Did you check if the size of some of our images changed?

I would prefer if we wait 1 months till we drop gcc 9 and binutils 
2.35.1, if we see some problems with gcc 10 and the new binutils we can 
easily try the intermediate versions if they are still included.

We can then remove gcc 7 and 9 and binutils 2.32 and 2.35.1.
