5dd941b311 Fix modulo by zero 
Yet another case caught by scan-build:

src/link/patch.c:188:21: warning: Division by zero
                        value = popRPN() % value;
                                ~~~~~~~~~^~~~~~~

Just copy over the code from the division case, with a few modifications.

f2be601a13 Check "left" boundary as well in isLocationSuitable 
"fixed" and "aligned" location checking advanced the target location to places
regardless of the associated free space, potentially breaking the assumption
that the location was always further in memory than the free space's base.

Rather than adding more code to try keeping that assumption true, harden
`isLocationSuitable` and handle that case as well.

50f091ab7c Fix RGBLINK failing to read args on certain machines 
`char` has implementation-defined signedness, and if it's chosen to be unsigned,
then -1 gets converted to 255, which is then promoted back to `int` as... 255,
always failing the loop condition in src/link/main.c:118
`int8_t` has the correct signedness, but considering `musl_getopt_long_only`
returns `int`, better use that so as not to lose any bits
