I don't know why "make boot" fails, but it sounds like you didn't
strip the debug info before compressing the kernel. From the Makefile:
objcopy --strip-all vmlinux vmlinux-tmp
mv vmlinux-tmp.gz vmlinux.gz
If you do this, the kernel should be a reasonable size.
Alternatively, drop -g from CFLAGS in the top-level Makefile (if you
_really_ don't want debug info).
