kbuild: enable use of AFLAGS and CFLAGS on commandline
The previous patches was preparation. With this patch we can now say: make CFLAGS=-Os vmlinux And the option specified will be appended to the options passed to gcc for C files. For assembler use: make AFLAGS=-foo vmlinux for the same functionality. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
