* config/tc-h8300.c (h8300_elf_section): New function - issue a
warning message if a new section is created without setting any
attributes for it.
(md_pseudo_table): Intercept section creation pseudos.
(md_pcrel_from): Replace abort with an error message.
* config/obj-elf.c (obj_elf_section_name): Export this function.
* config/obj-elf.h (obj_elf_section_name): Prototype.
* gas/elf/section0.d: Skip this test for the h8300.
* gas/elf/section1.d: Likewise.
* gas/elf/section6.d: Likewise.
* gas/elf/elf.exp: Skip section2 and section5 tests when the
target is the h8300.
* ld-scrips/sort.exp: Skip these tests when the target is the
h8300.
