Avoid longjmp()-catching compilation errors in cross-ports.
* doc/gdbint.texinfo: Update GET_LONGJMP_TARGET, L_SET doc. * irix4-nat.c, mips-nat.c (JB_ELEMENT_SIZE, get_longjmp_target): Move from mips-tdep.c and tm-{irix3,mips}.h. * mips-nat.c: Remove a bunch of code that was ifdef'd out of native MIPS ports. * nm-irix3.h, nm-mips.h (GET_LONGJMP_TARGET): Move from tm-irix3.h and tm-mips.h. * ultra3-nat.c (register_addr): Move from ultra3-xdep.c. (fetch_core_registers): Fix bfd_seek arguments.
