I have been trying CPU transparency mode (
http://maemo-sdk.garage.maemo.org/cpu-transparency-guide.html), which gets
me significantly further in the build process. (Basically, it set up an sshd
process on the device and copy binaries files over so they can run natively
instead of emulating them.)

When running natively, I can load the minimal lisp image and start
compiling... Unfortunately, the process is a bit finicky and I keep getting
errors like the following if I let the device sleep too long.

;;; Internal error: Read or write operation to stream #<output stream
#P"build:lsp;predlib.h.NEWEST"> signaled an error.
;;; Explanation: Transport endpoint is not connected.
;;; Internal error: Cannot close stream #<output stream
#P"build:lsp;predlib.h.NEWEST">.
;;; Explanation: Transport endpoint is not connected.
;;; Internal error: Read or write operation to stream #<output stream
#P"build:lsp;predlib.c.NEWEST"> signaled an error.
;;; Explanation: Transport endpoint is not connected.
(compile-file "src:lsp;seq.lsp" :output-file #P"build:lsp;seq.o.NEWEST"
:SYSTEM-P T :C-FILE T :DATA-FILE T :H-FILE T)

Filesystem error with pathname "src:lsp;seq.lsp".
Either
 1) the file does not exist, or
 2) we are not allow to access the file, or
 3) the pathname points to a broken symbolic link.
