OK, in these lines:
+ dummy := $(if $(shell cd $(PWD); test -d $(O) || echo $(O)),$(error O=$(O) does not exist),)
+ ABSOLUTE_O := $(shell cd $(PWD); cd $(O) ; pwd)
I changed both "cd $(PWD)" to "echo $(PWD)" and did
$ make O=BUILD -C tools/bootconfig/
and this is the build log:
make: Entering directory '/home/rdunlap/lnx/next/linux-next-20200306/tools/bootconfig'
cc ../../lib/bootconfig.c main.c -Wall -g -I./include -o bootconfig
make: Leaving directory '/home/rdunlap/lnx/next/linux-next-20200306/tools/bootconfig'
Does that help?
Thanks.
