[U-Boot] [PATCH 1/1] efi_loader: avoid make race condition

[Heinrich Schuchardt]

When building .efi targets a race condition was observed:

If %_efi.so is not yet built before trying to build %.efi and error
*** No rule to make target '%.efi'
occurs. By explicitly adding %_efi.so to the targets this is avoided.
