    The use of &[1]uintptr{fn} was causing sigfwd to allocate memory, even
    though it is being compiled for the runtime package.  That is a bad
    idea for this function, which is invoked by a signal handler.  Rewrite
    it to use only constructs that do not allocate memory when compiled
    for the runtime package.

Due to an oversight, the changes to use the new CPU generation tables
forgot to handle selecting a scheduler for a CPU other than the named
CPU target.  This meant that if, say, cortex-a12 was used, the null
scheduler was chosen rather than cortex-a17's scheduler as intended.
The fix is to correctly use the 'tune for' field when generating the
target-specific data files.

This revealed a spelling mistake in the name of the tune target in
cortex-m0.small-multiply.
