PDP-11 ABI for cross compiler

[Aram Havarneanu]

Right, so I used aout, compiled binutils, but gcc build fails with:

cc -c   -O2 -pipe -fno-strict-aliasing -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE  -W
-Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-defin

Build options were:

	--target=pdp11 \
	--enable-languages="c" \
	--with-system-zlib \
	--disable-nls \
	--with-libiconv-prefix="/usr/local" \
	--without-included_gettext \
	--with-newlib \
	--with-dwarf2 \
	--disable-shared \
	--with-gmp="/usr/local" \
	--with-mpfr="/usr/local" \
