Hi
The master doesn't build for sparc/leon3 when multiprocessing is
enabled.
It builds if you use --enable-multiprocessing without --enable-smp.
Based upon the error, there is likely user guidance needed
in the manual. For other methods removed, guidance on updating
code has been added. I didn't look to check in this case.
