Alex Kiernan 7f8185aa87 uboot-sign: Fix build when UBOOT_DTB_BINARY is empty
When UBOOT_DTB_BINARY is empty and because the code now changes
directory into ${B}, the test for the existence becomes `[ -f ]` which
succeeds and subsequently the install fails.

Reorder the code so it's clear that UBOOT_DTB_BINARY empty is an
expected configuration and then quote UBOOT_DTB_BINARY everywhere so
no one trips over this again.

Fixes: bacb59079eb6 ("uboot-sign: add support for different u-boot configurations")

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
