Description:	When cross-compiling, it is usually necessary to pass extra CFLAGS and LDFLAGS to the build system from the parent build environment, in this case, the FreeWRT ADK (trunk version). Attached is a patch to provide this ability; feel free to solve this with a different way though. Cause of the problem: while CFLAGS and LDFLAGS are passed by environment, the Makefiles do not add to them with += but overwrite or just don't use them, so we have to pass them as an additional make flag. This patch is currently part of the FreeWRT ADK; I hereby submit it for inclusion into upstream on behalf of the author, my employer. ****** STEPS TO REPRODUCE ****** Try to pass extra CFLAGS to the Asterisk build system. ****** ADDITIONAL INFORMATION ****** --- asterisk-1.4.0.orig/Makefile        2006-12-22 23:33:46.000000000 +0100 +++ asterisk-1.4.0/Makefile     2007-01-15 12:34:22.000000000 +0100 @@ -180,6 +180,10 @@ ifeq ($(OSARCH),linux-gnu)   endif endif +# fix for cross compiling +ASTCFLAGS+= ${EXTRA_CFLAGS} ${EXTRA_CPPFLAGS} +ASTLDFLAGS+= ${EXTRA_LDFLAGS} + ASTCFLAGS+=-pipe -Wall -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations $(DEBUG) ASTCFLAGS+=-include $(ASTTOPDIR)/include/asterisk/autoconfig.h
