[CI] Update to latest toolchain build
This toolchain build is significantly different from the previous one:
the toolchain is now built with crosstool-NG (instead of the SiFive
custom Makefile flow). The most significant changes are:
- GCC 9.2
- Better compatibility between distributions: the toolchain now works
on non-Ubuntu/Debian distributions. (That's not a problem in CI, but
for some of our collaborators on their local machines.)
