Subject: [PATCH] dtc: Fix Makefile to add CFLAGS not override
|
|
Makefile override CFLAGS not extend them, so some of them
|
missing. Sources builds out of kernel tree and probably not all
|
options could be used (?). We need at least -fmacro-prefix-map/
|
debug-prefix-map to eliminate absolute path in binaries.
