Hmmm, slight concern that I'm not sure how many timezones we should expect to be
installed in a test environment.

I'm back poking at mkroot and trying to turn it into a test environment that can
run the full toybox test suite under qemu, so I can finally have some proper
tests for mount and insmod and such. It's a musl-based environment, and I dunno
what musl does about timezones? (Glibc needs horrible generation and files and
such, and uClibc _copied_glibc's_data_at_install_time_ off the build system,
which was just crazy from a licensing perspective.)

Hey Rich: musl timezones? Do I have to do anything special, or what?
