Makefile: append the CFLAGS to existing ones
|
||
|
|
|
||
|
|
Allow the user to pass custom CFLAGS (eg. optimisation flags).
|
||
|
|
|
||
|
|
Do not use EXTRA_CFLAGS, append to existing CFLAGS with += (Arnout)

Patch not sent upstream.

Although not specific to buildroot, I am not sure this is the best
|
||
|
|
way to handle user-supplied CFLAGS.
