When mapping one (from) virtual address range to another (to) virtual
address range, be mindful of which mapper type to use for each range.
Before this, the same mapper type was used for both ranges. This meant
that if from and to were different (as in not both kernel virtual
addresses or user virtual addresses) then it would appear that either
from or to was not mapped previously and the kernel would panic.

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.
