Overloading _SCRIPTS is similar to what I did with overloading
BUILT_SOURCES. I'm still left with the issue that crt1.o and crt2.o
are not built from crt1.c and crt2.c.

Perhaps I could use BUILT_SOURCES for its real intent and actually
create crt1.c and crt2.c from crtexe.c by simply doing:

crt%.c:
    cp crtexe.c $@

But even there, I'm left with the original issue that I then need to
compile crt1 and 2.c into crt1.o and crt2.o.
