Build: restructure dependency builds for Linux

This reduces the size of files to be cached between builds by the CI system. The scripts are flexible enough so they can also be used by developers locally.

+# Purpose of 3rdParty
+
+This directory is used to download and build dependencies for BOINC components.
+Archives should be downloaded into a platform specific subdirectory (e.g linux, mac, ...)
+to allow cross compilation of several platforms on a single host.
+
+Build products of dependencies should be installed into a corresponding subdirectory of
+3rdParty/buildCache to allow CI systems to cache this data between BOINC builds.
+
+See the existing [buildLinuxDependencies.sh](buildLinuxDependencies.sh) and
+[buildMacDependencies.sh](buildMacDependencies.sh) scripts for how this is done
+on Linux and Mac currently.
