Allow CFLAGS/CPPFLAGS to be completed from the environment
|
||
|
|
|
||
|
|
Buildroot passes its own CPPFLAGS and CFLAGS in the environment, so
|
||
|
|
the CFLAGS += and CPPFLAGS += statements in gnu-efi Makefile have no
|
||
|
|
effect. Change these to override <VARIABLE> += so that they extend the
|
||
|
|
flags passed by Buildroot.
