OpenSBI r= equires the gcc toolchain to build correctly. Set TOOLCHAIN
explicitly t= o prevent build failures when using alternative
toolchains.

I am assuming you are having issues compi= ling it with clang, it would be good to document whats going wrong.
Since it's a bug to address, openSBI does not intend to use a parti= cular compiler.
 

We are figuring out the linker issue when Clang is used as the= default=20 toolchain. We haven't taken the time to figure it out yet.

Thomas Perrot
