ld error because of script.goiltemplate

[LMG]

I've noticed an issue with script.goiltemplate for the stm32f407 target, although taking a quick glance at other architectures it seems present as well.

The code starting at line 252 of script.goiltemplate will cause an error upon evaluating __SEG_ALIGN_% !proc::KIND %_% !proc::NAME %_STACK_RGN (namely in the previous ALIGN referencing it) if the size of the stack section is bigger than 4K.

I am unsure if the stack size can/should be that high, but in any case it is causing hard to understand errors.
It could be fixed by either outputting an error or giving a default value to __SEG_SIZE_% !proc::KIND %_% !proc::NAME %_STACK_RGN
