Output sections without any input sections to initialise their flags have their flags initialised by data statements to LOAD, ALLOC, HAS_CONTENTS by default. This is wrong for .comment. Fix that by making the script initialise the section type to INFO, one of the noalloc section types. That also allows the address of .comment to be set to zero, as is usual for non-alloc sections. Also, use source_sh for all of the sourced scripts to set up make dependencies. PR 30187 * scripttempl/misc-sections.sc: Set .comment address to zero and type to INFO. * scripttempl/ft32.sc: Fix breakages from last edit. * scripttempl/arclinux.sc: Use source_sh to source DWARF.sc and misc-sections.sc. * scripttempl/avr.sc: Likewise. * scripttempl/dlx.sc: Likewise. * scripttempl/elf.sc: Likewise. * scripttempl/elf32cr16.sc: Likewise. * scripttempl/elf32crx.sc: Likewise. * scripttempl/elf32msp430.sc: Likewise. * scripttempl/elf64bpf.sc: Likewise. * scripttempl/elf64hppa.sc: Likewise. * scripttempl/elf_chaos.sc: Likewise. * scripttempl/elfarc.sc: Likewise. * scripttempl/elfarcv2.sc: Likewise. * scripttempl/elfd10v.sc: Likewise. * scripttempl/elfd30v.sc: Likewise. * scripttempl/elfm68hc11.sc: Likewise. * scripttempl/elfm68hc12.sc: Likewise. * scripttempl/elfm9s12z.sc: Likewise. * scripttempl/elfmicroblaze.sc: Likewise. * scripttempl/elfxgate.sc: Likewise. * scripttempl/elfxtensa.sc: Likewise. * scripttempl/epiphany_4x4.sc: Likewise. * scripttempl/i386beos.sc: Likewise. * scripttempl/i386go32.sc: Likewise. * scripttempl/ia64vms.sc: Likewise. * scripttempl/ip2k.sc: Likewise. * scripttempl/iq2000.sc: Likewise. * scripttempl/mep.sc: Likewise. * scripttempl/mmo.sc: Likewise. * scripttempl/nds32elf.sc: Likewise. * scripttempl/pru.sc: Likewise. * scripttempl/v850.sc: Likewise. * scripttempl/v850_rh850.sc: Likewise. * scripttempl/visium.sc: Likewise. * scripttempl/xstormy16.sc: Likewise. * scripttempl/z80.sc: Likewise. * testsuite/ld-scripts/ld-version-2.d: Don't skip ft32 or pru.
