Mike,

Because it's broken with respect to how the rest of U-Boot is built. I already specify the cross-compiler via CROSS_COMPILE when I build u-boot.bin and u-boot.img, that I need to specify the same compiler in two different ways to build executables for the same target platform is broken and, it sounds like, as are the rest of the tools subdirectories.

If fw_setenv were a build host-based tool or if it made sense as a build host-based tool, then using HOSTCC would be sensible.

Best,

Grant
