Unify all assembler file generators

They now generally conform to the following argument sequence:

script.pl "$(PERLASM_SCHEME)" [ C preprocessor arguments ... ] \
$(PROCESSOR) <output file>

However, in the spirit of being able to use these scripts manually,
they also allow for no argument, or for only the flavour, or for only
the output file. This is done by only using the last argument as
output file if it's a file (it has an extension), and only using the
first argument as flavour if it isn't a file (it doesn't have an
extension).

While we're at it, we make all $xlate calls the same, i.e. the $output
argument is always quoted, and we always die on error when trying to
start $xlate.

There's a perl lesson in this, regarding operator priority...

This will always succeed, even when it fails:

open FOO, "something" || die "ERR: $!";

The reason is that '||' has higher priority than list operators (a
function is essentially a list operator and gobbles up everything
following it that isn't lower priority), and since a non-empty string
is always true, so that ends up being exactly the same as:

open FOO, "something";

This, however, will fail if "something" can't be opened:

open FOO, "something" or die "ERR: $!";

The reason is that 'or' has lower priority that list operators,
i.e. it's performed after the 'open' call.

Fix some assembler generating scripts for better unification

Some of these scripts would recognise an output parameter if it looks
like a file path. That works both in both the classic and new build
schemes. Some fo these scripts would only recognise it if it's a
basename (i.e. no directory component). Those need to be corrected,
as the output parameter in the new build scheme is more likely to
contain a directory component than not.
