Zero page start can't be adjusted

[SvOlli]

Hello!

On my Sorbus Computer, these changes break TaliForth2 in a way that it compiles, but cannot be executed. It runs in some kind of BRKs throwing execution off rails.

Build binary crashes (2024-06-05)

Build binary works (2024-05-31)

I couldn't dissect this further, because in between the code does not compile.

While writing this up, I could figure out the problem: the Sorbus Computer has some reserved zero page addresses at $0000-$000f. This can't be changed in the config file.

What is the best way to fix this? Have ram_start be defined as ?= instead of =, so it can be overwritten in the config?
