| Subject: [PATCH] Makefile: Add EXTRA_CFLAGS variable |
| |
| Distributions packaging dtc may need to set extra flags. Currently when |
| they do that it overrides the ones set by the makefile. This is |
| particularly problematic when compiling without yaml, as the yaml |
| detection is ignored. |
| |
| ld: dtc.o: in function `main': |
| dtc.c:(.text.startup+0x718): undefined reference to `dt_to_yaml' |
| |
| This patch provides a EXTRA_CFLAGS variable that is added to the list of |
| CFLAGS, and can be set on the command line when packaging. |
