Scott Weaver da0ce760c5 bitbake: fetch2: add check for empty SRC_URI hash string
No error was being reported when the hash string was set to empty.
For example: SRC_URI[md5sum] = ""

On a related note (not a bug):
Because whitespace in the string will result in a checksum mismatch, the error
message was updated to make it a little clearer why the error was thrown.
For example: SRC_URI[md5sum] = " " or
SRC_URI[md5sum] = " 209f8326f5137d8817a6276d9577a2f1"

Now creates a message like this:
File: '/home/scott/yocto-cache/downloads/rsync-3.2.3.tar.gz' has md5
checksum '209f8326f5137d8817a6276d9577a2f1' when ' 209f8326f5137d8817a6276d9577a2f1' was expected

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.
