Looking at the target name "u-boot-tools-1_2018.11-r0 do_compile"
I think it might have something to do with bump of U-Boot to v2018.11
and the error message in question was added in v2018.11-rc1,
see http://git.denx.de/?p=u-boot.git;a=commitdiff;h=a4958a71017fb142542f977c843c5fce769fc6ea

The problem is we use "sandbox_defconfig" as a dummy defconfig
because otherwise (not configured) U-Boot's build-system won't
allow us to proceed and in its turn mentioned patch adds a check
for a target platform like "if defined(__x86_64__)" which
we essentially don't satisfy and so we fail.

There're the following solutions:
 1. Revert mentioned patch
 2. Disable "CONFIG_EFI_LOADER"

Reverting is not nice and not future-proof.
Disabling of "CONFIG_EFI_LOADER" might be done in a couple of ways
like:
 1. Patching sandbox_defconfig
 2. Filtering "CONFIG_EFI_LOADER" from "sandbox_defconfig" right before
    execution of "make sandbox_defconfig"

I think latter option is the simplest and cleanest.

Should I send a patch for that?
