[U-Boot] Building for several archs

[Fabio Estevam]

Hi,

I am working on a patch series that I need to test across several
architectures (Need to build all the boards that select
CONFIG_SPI_FLASH_STMICRO).

I started trying to accomplish this task with buildman and it failed
to build. After that I tried building it manually.

I am getting the following errors on top of head U-boot:

m68k:

powerpc:

With these toolchains I am able to build the kernel without issues.

Any ideas?

Thanks,
