[U-Boot] toolchain problems when building iMX6 mx6qsabreauto (and another bootloader tool)

[Abraham V.]

Thanks Stefano,

I didn't notice that difference until you pointed it out. Till now, I was
under the assumption that both toolchains were (feature-wise) identical.
And I *almost* sent a complaint letter to Linaro about this too ... Guess,
I've got more to learn than I anticipated.

Sincerely,
Abraham V.
