Can you try using $(TARGET_CONFIGURE_OPTS) instead, so that CFLAGS and
al. are also passed?

Something like:

	$(MAKE) $(TARGET_CONFIGURE_OPTS) CFLAGS="$(TARGET_CFLAGS) -D__i386__" -C $(@D) all

I'm a bit surprised by the -D__i386__, because this is normally defined
by the compiler. Why is it needed?

See:

thomas at skate:/tmp$ cat toto.c 
#ifdef __i386__
#error "You are on x86"
#elif defined(__x86_64__)
#error "You are on x86-64"
#elif defined(__arm__)
#error "You are on ARM"
#endif
thomas at skate:/tmp$ ~/x-tools/ia32-2012.03/bin/i686-pc-linux-gnu-gcc -c toto.c 
toto.c:3:2: error: #error "You are on x86"
thomas at skate:/tmp$ ~/x-tools/ia32-2012.03/bin/i686-pc-linux-gnu-gcc -m64 -c toto.c 
toto.c:5:2: error: #error "You are on x86-64"
thomas at skate:/tmp$ ~/x-tools/arm-2011.03/bin/arm-none-linux-gnueabi-gcc -c toto.c 
toto.c:7:2: error: #error "You are on ARM"

Best regards,
