[U-Boot] [PATCH] tegra: Indicate that binman makes all three output files

[Simon Glass]

Use GNU make pattern rules to indicate that a single run of binman
produces all three Tegra output files. The avoids make running binman
three times (perhaps in parallel) and those instances inteferring with
each other.

See http://patchwork.ozlabs.org/patch/944611/ for the bug report.

(This make feature is very odd; specifying n targets without a % means 
they're separate rules, but specifying n targets with a % means it's a 
single rule that generates n targets. Nice inconsistency on make's part!)

Any chance we can apply this ASAP to the main u-boot.git master branch? 
Pretty much all my Jenkins builds are failing some random subset of 
boards because of this issue. Thanks.

If Tom W is fine, I'm happy to pick it up directly.

I don't usually weigh in on makefile issues, but if Stephen says it's needed, let's get it in.

I know. It's like they are trying to reuse syntax across different
functionality. I don't really understand why, but there might be a
theoretical basis.

Applied to u-boot/master, thanks!
