Update soruces to make alpha, arc and arm targets compile cleanly
with -Wc++-compat:
* config/tc-alpha.c: Add casts.
(extended_bfd_reloc_code_real_type): New type. Used to avoid
enumeration conversion warnings.
(struct alpha_fixup, void assemble_insn, assemble_insn)
(assemble_tokens): Use new type.
* ecoff.c: Add casts. (mark_stabs): Use enumeration names.
* config/obj-elf.c: Add cast
* config/tc-arc.c: Add casts.
* config/obj-aout.h (text_section,data_section,bss_section):
Make extern.
* config/obj-elf.c: Add cast.
* config/tc-arm.c: Add casts.
(X, TxCE, TxCE, TxC3, TxC3w, TxCM_, TxCM, TUE, TUF, CE, CL, cCE)
(cCL, C3E, xCM_, nUF, nCE_tag): Change input format to avoid the
need for keywords as arguments.
* ecoff.c: Add casts.
* ecofflink.c: Add casts.
* elf64-alpha.c: Add casts.
(struct alpha_elf_got_entry, struct alpha_elf_reloc_entry): Move
to top level.
(SKIP_HOWTO): Use enum name.
* elf32-arm.c: Add casts.
(elf32_arm_vxworks_bed): Update code to avoid multiple
declarations.
(struct map_stub): Move to top level.
* arc-dis.c Fix casts.
* arc-ext.c: Add casts.
* arm-dis.c (enum opcode_sentinel_enum): Gave name to anonymous
enum.
* emultempl/armelf.em: Add casts.
