configure.in (i[34567]86-*-freebsdelf): Don't include linux.h, i386/freebsd-elf.h no longer requires it.
* configure.in (i[34567]86-*-freebsdelf): Don't include linux.h,
i386/freebsd-elf.h no longer requires it. Instead include svr4.h.
* configure: Rebuilt.
* i386/freebsd-elf.h (DEFAULT_VTABLE_THUNKS): Define.
(ASM_COMMENT_START, ASM_APP_ON, ASM_APP_OFF, SET_ASM_OP): Likewise.
(PREFERRED_DEBUGGING_TYPE, WCHAR_UNSIGNED): Likewise.
(SWITCH_TAKES_ARG): Likewise.
* i386/freebsd.h: Remove FREEBSD_NATIVE support.
* config/t-freebsd: Moved from config/i386/ so it can used for all
FreeBSD targets.
