fdt: Ensure that libfdt_env.h comes from U-Boot
adds libfdt_env.h to HOSTCPPFLAGS. The causes a problem with one of our older hosts. On the old hosts, getline prototype is protected by
#ifdef __USE_GNU
This should be OK if the C file has #define _GNU_SOURCE. However, because of your patch, the stdio.h is included before _GNU_SOURCE is defined. The result is warnings like this
aisimage.c: In function ‘aisimage_generate’: aisimage.c:313: warning: implicit declaration of function ‘getline’ kwbimage.c: In function ‘kwdimage_set_ext_header’: kwbimage.c:236: warning: implicit declaration of function ‘getline’ imximage.c: In function ‘parse_cfg_file’: imximage.c:430: warning: implicit declaration of function ‘getline’ pblimage.c: In function ‘pbl_parser’: pblimage.c:137: warning: implicit declaration of function ‘getline’ ublimage.c: In function ‘parse_cfg_file’: ublimage.c:179: warning: implicit declaration of function ‘getline’

I took a quick look at this. It seems that many of the host C files in tools/ define _GNU_SOURCE. Should we just move that #define to the Makefile?

Adding -D_GNU_SOURCE in Makefile can fix this problem.

No, but if you do a patch and cc me I will Ack it :-) Sorry but I can't actually test this case here.
