Hi Heinrich,
Thanks for taking a look.

... as I've described in
https://lists.denx.de/pipermail/u-boot/2018-March/323624.html
, the problem is that when recursive make is building lib/efi_loader,
arch/$(ARCH)/lib/$(EFI_CRT0) might not exist yet and the rule for building
it is only known by the recursive make responsible for building
arch/arm/lib.

It doesn't matter if it's a clean or incremental build. By increasing
the race window with this hacky patch (the ':=' -> '=' change is important):
