Please try this patch:

Which makes tools/power/acpi build more robust to survive toolchains that are not generated

Okay, I did a totally clean build (latest linux-next kernel and
buildroot) without mention patch and still see the issue described
below:

But reveals another, the output path is broken:

output/host/usr/bin/i586-buildroot-linux-uclibc-gcc -c -D_LINUX -I
$OUT/include -I $SRC/tools/power/acpi/../../../drivers/acpi/acpica
-Wall -Wst
rict-prototypes -Wdeclaration-after-statement -O1 -g -DDEBUG
-DACPI_APPLICATION -DACPI_SINGLE_THREAD -DACPI_DEBUGG
ER -I. -o $OUT/tools/acpidbg/acpidbg.o acpidbg.c
Assembler messages:
Fatal error: can't create $OUT/tools/acpidbg/acpidbg.o: No such file
or directory
../../Makefile.rules:26: recipe for target '$OUT/tools/acpidbg/acpidbg.o' failed

$OUT — path to O=
$SRC — path to kernel sources

From latest run

output/host/usr/bin/i586-buildroot-linux-uclibc-gcc -c -D_LINUX -I
$OUT/include -I $SRC/tools/power/acpi/../../../drivers/acpi/acpica
-Wall -Wst
rict-prototypes -Wdeclaration-after-statement -O1 -g -DDEBUG
-DACPI_APPLICATION -DACPI_SINGLE_THREAD -DACPI_DEBUGG
ER -I. -o $OUT/tools/acpidbg/acpidbg.o acpidbg.c

Of course it fails since proper folder name should be
'tools/power/acpi/tools' instead of 'tools'.
