There is a conflict between the static file lib/acpi/dsdt.c and the file dsdt.c generated dynamicaly by scripts/Makefile.lib. When a mrproper is done, the static file dsdt.c is removed. If a build with acpi enabled is launched after, the following error is raised:
CC lib/acpi/acpi_table.o make[2]: *** No rule to make target 'lib/acpi/dsdt.asl', needed by 'lib/acpi/dsdt.c'. Stop. scripts/Makefile.build:394: recipe for target 'lib/acpi' failed
To avoid such error, the static file dsdt.c is renamed to acpi_write_dsdt.c.
