	The envcrc.c does sizeof(unsigned long) when calculating the crc, but this is done with the build toolchain instead of the target tool chain, so if the build is a 64bit system but the target is 32bits, the size will obviously be wrong. This converts all unsigned long stuff related to crc32 to uint32_t types. Compile tested only: output of ./tools/envcrc when run on a 32bit build system matches that of a 64bit build system.
