[U-Boot] [BUG] efi_loader: self-tests fail on qemu-x86_defconfig when compiled with GCC 8.3 and CONFIG_CC_OPTIMIZE_FOR_SIZE=y

Debian has recently (march 8th) upgraded GCC from 8.2 to 8.3.

When I compile qemu-x86_defconfig with CONFIG_CC_OPTIMIZE_FOR_SIZE=y
some of the UEFI selftests (bootefi selftest) fail. It looks to me like
ebx is not conserved.

With CONFIG_CC_OPTIMIZE_FOR_SIZE=n everything is fine.

Best regards

Heinrich
