Hi everyone.
Solving other things, I have realized that all that problem on fast CC detection (CCFOUND) is easily solved by doing: CC := $(.................) instead of CC = $(.........) The find of the suitable CC command is repeated many times along a kernel build. And CC is not anything that can change along a kernel build. So former syntax solves all the problems, CC detection can be so complex as you want because is done only once.
Same is valid for other Makefile variables: CPP = $(CC) -E ===> CPP := $(CC) -E
(If you want to test how many shells are spawned when using CC, try CC = $(shell echo "===== CC EVAL ===============" >&2; if ........ vs CC := $(shell echo "===== CC EVAL ===============" >&2; if .......
Is there something I am missing ?
