[patch] Clean up NetBSD configs, fix NetBSD ELF configs

[Jason R Thorpe <thorpej at wasabisystems dot com>]

The following patch overhauls the NetBSD configs, most notably
splits a.out-specific bits into a separate file, and adds a new
netbsd-elf.h header for common NetBSD ELF definitions, so that
future NetBSD ELF configs can use the header-file-list method
more easily.

This also fixes some problems with the NetBSD alpha, i386, and mips
ELF configs, and adds support for NetBSD mipseb as a side-effect of
cleaning up the mips config.

Bootstrapped on alpha-unknown-netbsd, i386-unknown-netbsdelf, and
mipsel-unknown-netbsd.

	* config/netbsd.h (TARGET_HAS_F_SETLKW): define.
	Split a.out-specific bits into...
	* config/netbsd-aout.h: ...this.
	* config/netbsd-elf.h: New file.
	* config/alpha/netbsd-elf.h: Remove.
	* config/alpha/netbsd.h: Rewrite for a NetBSD/alpha ELF target.
	* config/i386/netbsd-elf.h (LIB_SPEC): Remove.
	(STARTFILE_SPEC): Remove redundant definition.
	(ENDFILE_SPEC): Likewise.
	(LINK_SPEC): Likewise.
	(CPP_SPEC): Likewise.
	(ASM_SPEC): Likewise.
	(LIB_SPEC): Likewise.
	(SWITCH_TAKES_ARG): Likewise.
	(TARGET_MEM_FUNCTIONS): Likewise.
	(CPP_PREDEFINES): Redefine.
	(ASM_FINAL_SPEC): Remove redefinition.
	(ASM_COMMENT_START): Redefine.
	(FUNCTION_PROFILER): Define.
	(TARGET_VERSION): Redefine.
	Comment and formatting cleanup.
	* config/i386/netbsd.h: Include <netbsd-aout.h>.
	* config/m68k/netbsd.h: Include <netbsd-aout.h>.
	* config/mips/netbsd.h: Rewrite for NetBSD/mips ELF target,
	big- or little-endian.
	* config/ns32k/netbsd.h: Include <netbsd-aout.h>.
	* config.gcc (*-*-netbsd*): Add definitions common to all
	NetBSD configs.
	(alpha*-*-netbsd*): Remove redundant xm_defines, gas, and
	gnu_ld definitions.  Add netbsd-elf.h to and remove
	alpha/netbsd-elf.h from tm_file.  Remove alpha/t-crtfm from
	tmake_file, and don't lose previous tmake_file contents.
	(arm*-*-netbsd*): Add netbsd-aout.h to tm_file.
	(i[34567]86-*-netbsdelf*): Remove redundant xm_defines, gas, and
	gnu_ld definitions.  Add netbsd-elf.h to tm_file.
	(mips-dec-netbsd*): Remove as alias for mipsel-*-netbsd*.
	(mipsel-*-netbsd*): Rename this to...
	(mips*-*-netbsd*): ...this.  Add elfos.h to tm_file.  Add
	mips/little.h to tm_file for mips*el-*.
	(powerpc-*-netbsd*): Remove redundant xm_defines definition.
	(sparc-*-netbsd*): Add netbsd-aout.h to tm_file.
	(vax-*-netbsd*): Add netbsd-aout.h to tm_file.
