The tools (such as mk_dsdt) can be cross-built when it may not be
desirable to build them on the target.
The commit c4ac1077 "libxl/arm: Generate static ACPI DSDT table"
introduced support of ARM64 in mk_dsdt but also break cross-building
tools because the ACPI tables are not correct.
While mk_dsdt should generate ACPI table for the target architecture, it
currently generates the one for the host. This is because the source
code contains reference to the host architecture (__aarch64__,
__x86_64__, __i386__) when it should be the target architecture.
Replace all __aarch64__, __x86_64__, __i386__ by the corresponding
CONFIG_*.
Also expose the CONFIG_* to the source code as the currently only
exposed to the Makefile.
