Remove the SVR4 macro. Move the kernel INTERRUPT_INPUT bug note to

the new file dgux5-4R2.h where it belongs.  Set INTERUPT_INPUT as the
default.  Remove the editorial comments about GNU malloc.  Set
ORDINARY_LINK and move the conditional comment to DGUX5-4R2.h.  Remove
C_COMPILER, LINKER and MAKE_COMMAND.  Add the SVR4 macro inside the
ELF part of te conditional.
