* configure.in (*-*-sunos*): Use trailing * to match all
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.
