ACPI sources will be available to various component which will build
them according to their own rules. ACPI's Makefile will only generate
necessary source files.

v2:
* Reordered .gitignore changes alphabetically
* Dropped trailing slashes
* Use relative path for ACPI_PATH
* Use $(addprefix...)
* Dropped use of 'cd' in rules and instead add $(ACPI_BUILD_DIR)/ to $*
