Subject: Load builderrc from sys_data_dir to avoid the need of copying it to $HOME
X-Git-Tag: 1.0~25
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=f0042e452d1d2771eebbc9c54bd90e5218836a8b;p=builder.git

Load builderrc from sys_data_dir to avoid the need of copying it to $HOME
Do not incorporate the from path in include hash for <> includes
Fix an error with C++ include path construction
Use package-relative filenames for storing dependencies
Detect if dependencies are ot found in deps cache and find them
