Building mkimage alone without having to set up the rest, on OSX.

Somehow it doesn't get used here:

$ make tools
make -C tools all
/Volumes/Data/devel/u-boot/u-boot/common/env_embedded.c:28:20: error: config.h: No such file or directory

make: *** [tools] Error 2

2nd pass (it doesn't like dep stuff):

$ make tools
make -C tools all
gcc  -g  -Os   -D__KERNEL__ -I/Volumes/Data/devel/u-boot/u-boot/include -fno-builtin -ffreestanding -nostdinc -isystem /usr/lib/gcc/i686-apple-darwin10/4.2.1/include -pipe  -Wall -Wstrict-prototypes -fno-stack-protector   -o crc32.o crc32.c -c

Been this way for a year at least, never managed to build it before.
I recall trying passing all sort of stuff to make, probably after asking on IRC but it didn't make it either.
