tools/power/acpi: Serialize Makefile
Before this patch you get tools/power/acpi/Makefile.rules
included in parallel trying to copy KERNEL_INCLUDE multiple
times:
make -j20 acpi
DESCEND power/acpi
DESCEND tools/acpidbg
DESCEND tools/acpidump
DESCEND tools/ec
MKDIR include
MKDIR include
MKDIR include
CP include
CP include
cp: cannot create directory '/home/abuild/rpmbuild/BUILD/linux-5.7.7+git20200917.10b82d517648/tools/power/acpi/include/acpi': File exists
make[2]: *** [../../Makefile.rules:20: /home/abuild/rpmbuild/BUILD/linux-5.7.7+git20200917.10b82d517648/tools/power/acpi/include] Error 1
make[1]: *** [Makefile:16: acpidbg] Error 2
make[1]: *** Waiting for unfinished jobs....
with this patch each subdirectory will be processed serialized:
DESCEND power/acpi
DESCEND tools/acpidbg
MKDIR include
CP include
CC tools/acpidbg/acpidbg.o
LD acpidbg
STRIP acpidbg
DESCEND tools/acpidump
CC tools/acpidump/apdump.o
...
LD acpidump
STRIP acpidump
DESCEND tools/ec
CC tools/ec/ec_access.o
LD ec
STRIP ec
