    libgloss: msp430: delete custom .S.o rule
    
    This was added to specify -Wa,-gdwarf2 when compiling the assembly
    files.  Considering the size of these .S files, it seems unnecessary
    overkill and complicates the build system.  All but one of these
    compile down to 6 or fewer lines, and those hardly need extra debug
    for anyone who is poking msp430 assembly.  The 1 file that is larger
    than that (crt_move_highdata.S) is still <15 insns.
    
    This will also simplify merging it into the top-level Makefile.
