Fix broken -Bsymbolic-functions
For selected targets. The testcase reveals a number of targets that still need fixing. bfd/ * elf32-arm.c (elf32_arm_final_link_relocate): Use SYMBOLIC_BIND to check if a symbol should be bound symbolically. * elf32-hppa.c (elf32_hppa_check_relocs, elf32_hppa_adjust_dynamic_symbol, elf32_hppa_relocate_section, elf32_hppa_finish_dynamic_symbol): Likewise. * elf32-m68k.c (elf_m68k_check_relocs, elf_m68k_relocate_section): Likewise. * elf32-nios2.c (nios2_elf32_relocate_section, nios2_elf32_check_relocs, allocate_dynrelocs): Likewise. * elf32-tic6x.c (elf32_tic6x_finish_dynamic_symbol, elf32_tic6x_relocate_section): Likewise. ld/testsuite/ * ld-elf/symbolic-func.s, * ld-elf/symbolic-func.r: New test. * ld-elf/elf.exp: Run it.

+# Most targets will emit an R_*_RELATIVE reloc here, but RELATIVE

+# defining an ADDR32 or ADDR64 style reloc without a symbol to behave
+# like a RELATIVE reloc. GLOB_DAT relocs are similarly superfluous.
+# In fact, a RELATIVE reloc can be wrong even if a target does have
+# them, if the 32-bit or 64-bit field being relocated is unaligned.
+# In that case the target ought to emit a UADDR32/64 or similar rather
+# than a RELATIVE reloc.

+# We also allow a dynamic reloc with a reference to .text as that
+# should also resolve correctly. No reloc, or one referencing "fun"
+# is incorrect. Also fail the test on finding a reloc at offset 0,
+# typically a NONE reloc.
