But is that a script that is stored somewhere, or is it just a setting inside 
your Jenkins installation?

Yes, a.out support (which is used on Atari) has been dropped in 2.31. But i've 
added it back in, and cross-binutils of 2.34 can be found at http://tho-otto.de/crossmint.php#binutils 

That does not mean that the section based linking will work. I'll have to 
check whether that can somehow be supported.

Yes, but when i use gas, i think fpc won't generate the required section 
directives?

ie. when using -Avasm:

	.file "system.pp"
# Begin asmlist al_pure_assembler

.section .text.n_system_$$_get_caller_addr$pointer$pointer$$pointer,"awx"
	.balignw 4,0x4e71
.globl	SYSTEM_$$_GET_CALLER_ADDR$POINTER$POINTER$$POINTER
SYSTEM_$$_GET_CALLER_ADDR$POINTER$POINTER$$POINTER:
	link.w	%a6,#-4
#  CPU 68000
	move.l	%a0,%d0
	tst.l	%d0
	beq	.Lj1800_1
	move.l	%d0,%a0
	move.l	4(%a0),%d0
.Lj1800_1:
#  CPU 68000
	unlk	%a6
	rts


Without it:

	.file "system.pp"
# Begin asmlist al_pure_assembler

.text
	.balignw 4,0x4e71
.globl	SYSTEM_$$_GET_CALLER_ADDR$POINTER$POINTER$$POINTER
SYSTEM_$$_GET_CALLER_ADDR$POINTER$POINTER$$POINTER:
	link.w	%a6,#-4
#  CPU 68000
	move.l	%a0,%d0
	tst.l	%d0
	beq	.Lj1800_1
	move.l	%d0,%a0
	move.l	4(%a0),%d0
.Lj1800_1:
#  CPU 68000
	unlk	%a6
	rts
