[PATCH 1/3] scripts: Remove build_parallel

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

We are happily building multiple images in parallel by now, without any
indication that things are needlessly serialized. This likely dates back
to the situation, possibly both in bitbake and Isar, at the time the
script was merged.

-The BitBake revision included with Isar seems to serialize multiconfig builds.
-The following script may be used from the project directory (`isar`) to build
-multiple configurations in different build directories faster:
-
-```
-scripts/build_parallel ../build multiconfig:qemuarm-wheezy:isar-image-base \
-    multiconfig:qemuarm-jessie:isar-image-base \
-    multiconfig:qemuarm-stretch:isar-image-base \

 ### Generate full disk image
 
 A bootable disk image is generated if you set IMAGE_TYPE to 'wic-img'. Behind the scenes a tool called `wic` is used to assemble the images. It is controlled by a `.wks` file which you can choose with changing WKS_FILE. Some examples in the tree use that feature already.
