The current logic determining whether to use .machine in the generated
asm code puts it there if the compiler is not configured with a default
target cpu, _or_ no -mcpu= was given on the command line. It should
be "and" instead.

The compiler check that issued a duplicate declaration error for
a, a, a := 1, 2, 3
was incorrectly issuing an error for
a, a, a = 1, 2, 3
While this is not particularly useful, it is valid Go.
