[PATCH] Multiarch {elf,coff}_make_msymbol_special

[Elena Zannoni <ezannoni at localhost dot redhat dot com>]

I have multiarched these 2 macros, which are defined in the arm code,
because I need them for some upcoming SH patches.

Richard, I have not touched the arm-tdep.c file.

I'll commit this tomorrow, if there are no objections.

	* gdbarch.sh: Add definitions for COFF_MAKE_MSYMBOL_SPECIAL and
	ELF_MAKE_MSYMBOL_SPECIAL.
	* gdbarch.c, gdbarch.h: Regenerate.
	* arch-utils.c (default_elf_make_msymbol_special, 
        default_coff_make_msymbol_special): New functions.
	* arch-utils.h (default_elf_make_msymbol_special,
        default_coff_make_msymbol_special): Export. 
	* elfread.c (elf_symtab_read): Compile use of
	ELF_MAKE_MSYMBOL_SPECIAL unconditionally because it is now
	multiarched.
	* coffread.c (coff_symtab_read): Ditto, for
	COFF_MAKE_MSYMBOL_SPECIAL.
