sub-variants of SunOS, e.g. sunos4* to match sunos4.1.1.
(sparc-*-sunos3): Remove host & target. Sunos3 never shipped
in production on Sun-4.
({a29k,i[34]86,i960}-*-elf): Add targets, equivalent to coff.
(m68k-*-{aout,coff,elf}): Add targets, w/new config and tm files.
(sparc-*-{aout,coff,elf}): Add targets, w/new config and tm files.
* tm-68k-un.h, tm-68k-noun.h, tm-spc-un.h, tm-spc-noun.h: New
target definitions for embedded with and without underlines on
identifiers. FIXME -- this ought to be known by BFD instead.
* tm-sparc.h, tm-sun2.h, tm-sun3.h: Delete NAMES_HAVE_UNDERSCORE:
not a parameter of the CPU, but of the development environment.
* tm-es1800.h, tm-sunos.h, tm-vx68.h: Add NAMES_HAVE_UNDERSCORE.
