Hi,

like the HP-UX linker, the VMS linker doesn't deal well with named text sections.
So, always default to .text section on both Alpha and ia64 VMS.

Committed on trunk.

Tristan.

	* config/vms/vms-protos.h (vms_function_section): New prototype.
	* config/vms/vms.c (vms_function_section): New function.
	* config/vms/vms.h (TARGET_ASM_FUNCTION_SECTION): Define.
