Don't error out on conditional .include

The hard requirement that an .include statement cannot be inside of
another block was, in the end, a bit short-sighted. Imagine the
following block:

.ifdef DEBUG
    .include "debug.s"
.endif

This is perfectly sound-looking code, and it should not be punished as
the developer is doing something that is not bending the assembler in
weird ways. Hence, just nuke this check.
