Yes, there are new features when there are multiple sub-architectures.

Because it might be partially successful and you want to look at the 
generated objects?  In particular 'success' means that the primary 
sub-architecture is installed: others might fail.

Try INSTALL --clean, etc.  But I normally do this from a tarball to 
keep the sources clean and to test the reference sources.

There are a few improvements to R-patched in the detection of 
sub-architectures, so you might like to see if you prefer what it 
does.
