Add LINK_JOBS logic to all three builder scripts
The stress, helper and bisect build scripts needed the LLVM_LINK_JOBS option
to make sure it doesn't run out of memory while linking, especially in SoCs
that have a lot more cores than RAM (ex. HiKey).
This patch calculates the jobs by seeing how much RAM the target has and adding
+1, as link jobs rarely take more than 1GB, but the final ones do use several
hundred. Also making sure we don't exceed the number of cores.
A few other small changes:
* Replace "else if" by "elif"
* Build only minimal targets on ARM (even o full build)
* Fixed a -j$PARALLEL bug introduced by a prvious commit
* Converted a few backticks into $()
