link error while u-boot-spl build : undefined ref to `printf` or `strcmp` etc.

[Chan Kim]

Hello,

When I build u-boot, I get this error at the end. (during u-boot-spl build).

I've been fixing some link errors by adding config values but I can't figure
out what is wrong with this.

Below is the final command for u-boot-spl build and the error messages.

Can any expert tell me what can be wrong here?
