But building an Ada compiler works exactly the same as building C and
C++ compilers.  There should really be no difference.

I am aware that you have much experience building stuff.  But building
RISC-V is a little different than the others, because of link-time
relaxations deleting code, which means some things that work for other
targets don't work for RISC-V.  It is possible that the scheme you are
using to build canadian cross compilers will work for other targets
but not RISC-V because of this problem.  That is why I asked if this
is your first attempt to canadian cross build a RISC-V native
compiler.  And because of the above, that building Ada should be no
different from building C and C++.

Anyways, all I can repeat is what I've said before.  It works for me.
I can give you my trivial build scripts if you want.  Otherwise, you
have to give me enough info that I can reproduce the problem that you
ran into.
