f01a227470 Fix non-const labels with callbacks having incorrect values when diffed 
Basically, this broke PC, which is currently the only label-typed symbol
with a callback.

1d78cd0f03 Axe the constexpr expression evaluator 
This avoids redundancy between them (and also having to port fixes and features)

Make the bool field an actual bool

comments)

ed72baca2a Make more symbol functions const 
Can't hurt to specify those as they are now. Perhaps it'll enable slightly more

12f2f654dd Add -MG 
This option allows for automatic dependency detection and generation:
as soon as a missing file is found, it is output to the dep file, and
assembly immediately aborts. (No .o file is produced, even if `-o` was
speicified.) This doesn't cause an error, either; the point is that once
the file is added to the dep file, the Makefile is re-parsed, and this
time the file will be generated, so the dep list builds up automatically.
This mimicks GCC's option and behavior.

1fb9f90f0f Add -MT option 
Allows overriding the output file in dependencies, which also allows
outputting those without also outputting the object file.
This, again, mimicks GCC's option.

ab9307ac61 Clean up symbol management 
Stop using that bitfield for everything, including what can be determined otherwise
It also makes it easier to have a sane state, since some bits were (supposedly)
mutually exclusive

e3ef194b4f Remove local label error checking 
This is actually not necessary, because RGBLINK would warn about missing labels.
Besides, through semi-esoteric ways, it is possible to define more labels in this scope,
and there's no reason to prevent that.

faa7893761 Fix develop error in getopt_long_only 
The error was due to casting `const` away for permuting argv
elements, which is necessary for a libc for compatibility with older
systems, but not for us.

Checkpatch will complain about the style not being followed, but this is not
our code, so it can be ignored.
