The tiny geeky part in me could enjoy using a full z196 to cross
compile for an ARM phone :-)  It is very elegant that the toolchain
actually supports such a process.

When I did my cross compiles back in 1999, the hand-me-down laptop
outperformed the G4 CPU by enough that I could afford to share over
NFS and do unzipping and compiles on the latop :-)  That clearly shows
the expectation problems we had with Linux performance on the early
mainframe CPUs. The balance now is the other way: my current laptop
may be 2 times as fast, but the modern mainframe CPU gained a factor
20 since then. I envy my friends with a z196.
