a998adbb90 Set the alignment of the setjmp magic values correctly. The alignment needs 
to be before the lavel, otherwise an extra word may be added between the
label and the data.

d422e6f9b5 Add the start of libc and libstand for arm64. Not all of the machine 
dependent functions have been implemented, but this is enough for world.

8daa81674e Start to import support for the AArch64 architecture from ARM. This change 
only adds support for kernel-toolchain, however it is expected further
changes to add kernel and userland support will be committed as they are
reviewed.

As our copy of binutils is too old the devel/aarch64-binutils port needs
to be installed to pull in a linker.

To build either TARGET needs to be set to arm64, or TARGET_ARCH set to
aarch64. The latter is set so uname -p will return aarch64 as existing
third party software expects this.
