Hello
I encountered a race between targets scripts_basic and asm-generic (due -j2 make flag).
It happens when source tree is distcleaned (mrproper).
First job:
running target asm-generic to generate all wrappers in architecure include/generated.
Second job:
trying to compile empty.c since it is under target "always" which is dependency for __build.
The error is because empty.o depends on some headers from arch/<arch>/include/generated/asm/.
This race is rare and can be very annoying.
My naive patch for root Makefile is:
# Basic helpers built in scripts/
PHONY += scripts_basic
-scripts_basic:
+scripts_basic: asm-generic
$(Q)$(MAKE) $(build)=scripts/basic
$(Q)rm -f .tmp_quiet_recordmcount
