as far as I know gcc linker cannot read defines made in header, but you can add symbol definition to you linker using defsym

example :

in you project properties > C/C++ Build > Settings > Tools Sttings (tab) > MCU GCC Linker > Miscellaneous > Linker flags add

-Wl,--defsym,stack_size=0x2000

and in my linker I add this

stack_size = DEFINED(stack_size) ? stack_size : 0x400 ;
