With a custom crt0 you can do it, but you need to go to the asm level.
The linker sticks the segments together in the order they are first
mentioned - except when it doesn't: _CODE is a bit weird.
My Fuzix crt0 files start with stuff like
; Ordering of segments for the linker.
; WRS: Note we list all our segments here, even though
; we don't use them all, because their ordering is set
; when they are first seen.
.area _CODE
.area _CODE2
.area _VIDEO
.area _CONST
.area _INITIALIZED
.area _DATA
.area _BSEG
.area _BSS
.area _HEAP
etc, to force the order I want. The default crt0 does the same trick in
order to get GSINIT/GSFINAL right.
