I will do it.

I fixed these.

There are some flake8 errors in gdbarch-components.py, but I didn't fix
those.  Most of them are due to how the file is loaded by gdbarch.py,
and the remaining few are over-long comment lines that are pre-existing
buglets in gdbarch.sh, I think.

I don't mind tweaks, but we can also of course make changes afterward.

Fixed.
