Was using the incorrect USER_TLS_OFFSET instead of USER_TCB_OFFSET. In
any case, this is better done in process::clone.

build.rs: aarch64: Specify target for cc::Build
...
Oddly, not specifying this or using aarch64-unknown-none (which would be
the default that cc gets from the TARGET environment variable) both
fail to invoke the appropriate compiler to build the asm code.
Using aarch64-unknown-redox works but shouldn't really be needed. This
is perhaps because of some odd arrangement of KTARGET, TARGET, the
installed prefix toolchain and the kernel target JSON spec.
The early_init asm code shall be replaced by a pure Rust bootloader
eventually so let's move with this for the moment.

Implement Copy and Clone manually for BuddyEntry.
...
This fixes a warning that may in the future become an error, about the
possibility for unaligned references, since the derive macros apparently
rely on creating references to fields. Unaligned references are direct
UB.
