gold alignment for 64-bit target in 32-bit binary

If you try to link for a 64-bit target in a 32-bit gold binary, the
output views are not aligned enough so we die with a SIGBUS on
platforms like sparc.

Simple sparc test case:

-------------------- test.s --------------------
	.globl _start
_start:	nop
-------------------- test.2 --------------------

bash$ gcc -m64 -c -o test.o test.s
bash$ ./ld-new -o test test.o
Bus error (core dumped)

It seems things are 4-byte aligned when they need to be 8-byte
