From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx> This moves all generic path variables to a new the config/Paths.mk.in input source file to be processed at configure time, tons of files use these so this just share them. This also paves the way to let us easily dynamically configure these with autoconf, for now we leave the same presets as was present before. This work was prompted by looking for an autoconf way to do replacements for the hotplug global file, while at it I realized that a few other files use the same variables and have in places around the tree the same constructs for generating their own files. This makes use of the old buildmakevars2file() but generalizes the definition of the paths at configure time and spreads the new definitions out throughout the build system. This has no impact on building the hypervisor and extras/mini-os, you do not need to, and are not expected to, run configure to build those targets. While at it lets add some documentation on the for the two files on the source file, we can expand further details on the wiki [0].
