Parts of the code are using C99 constructs (such as variables declared inside loops), but also GNU extensions (such as typeof), so using -std=gnu99 is necessary to build with older versions of gcc that don't default to building with gnu99.
It fixes the following build failure:
./tools/../lib/crc16.c: In function "crc16_ccitt": ./tools/../lib/crc16.c:70:2: error: "for" loop initial declarations are only allowed in C99 mode for (int i = 0; i < len; i++) ^ ./tools/../lib/crc16.c:70:2: note: use option -std=c99 or -std=gnu99 to compile your code
when building the host tools with gcc 4.7.
