DEVTOOL_EXTRA_OVERRIDES only needs one entry for each instance of
overrides. Previous to these changes it would find every override to
SRC_URI and add it to the list. This would duplicate instances where
SRC_URI is modified multiple times with the same override like:
SRC_URI_append_foo += "file://0001-foo.patch"
SRC_URI_append_foo += "file://0002-bar.patch"
A bbappend might also overwrite a SRC_URI override, which would also
cause multiple instances to occur.
When there are multiple instances of the same override in
DEVTOOL_EXTRA_OVERRIDES it causes devtool modify to fail when creating
override branches. The failure occurs when attempting to create the same
override branch a second time and looks like this:

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.
