runtime: fix sigfwd to not allocate memory

    The use of &[1]uintptr{fn} was causing sigfwd to allocate memory, even

[ARM] Fix PR79742 incorrect scheduler choice.

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
