--- Comment #2 from Jim Wilson <wilson at gcc dot gnu.org> ---
riscv-unknown-linux-gnu is not a supported target.  You must use either
riscv32-unknown-linux-gnu or riscv64-unknwon-linux-gnu.  Both compilers support
both word sizes, the only difference is which is the default word size.  This
may be part of the reason why it failed.

The attachment doesn't show any ICE.  It is just a config.log file, and I don't
see anything interesting in there.

Note that mingw64 builds of a linux toolchain are unlikely to work as glibc
requires a case sensitive file system.  I'd suggest using WSL2 as something
more likely to work, but I haven't tried that myself.

It looks like you have a badly broken compiler build.  You will need to figure
out why it is broken.  This doesn't seem to be a gcc problem, but rather a
build problem on your side.
