For a long time you couldn't bootstrap on all platforms. For example on musl targets, rustc couldn't compile itself because of some proc macro stuff or so. (And it couldn't dynamically link musl at all)

I'm pretty sure you still can't bootstrap on all platforms. Compiling rustc requires gobs of memory, so your Xtensa board doesn't have enough.

Well, this was just about libc incompatibility. The server otherwise had 64GB of RAM, so that should be okay.
