Thanks for pointing this out. Looks like tegra has already definition in place for building without binman[1], so deleting 'select BINMAN' from arch/arm/mach-tegra/Kconfig lets the package build without swig.
After testing on the hardware, I'll send next iteration of the patches.

Following documentation[2] it needs libpcre, but I don't have any insight if we can rely on host library or should provide one in tools. Anyway U-Boot is building fine *for now* without it.

BTW Is there somewhere a list of packages installed on buildbots and is the list consistent across all of them?
