Add ${c,cxx}.deduplicate_export_libs() function
This function deduplicates interface library dependencies by removing libraries that are also interface dependencies of the specified libraries. This can result in significantly better build performance for heavily interface-interdependent library families (for example, like Boost). Typical usage: import intf_libs = ... import intf_libs += ... ... import intf_libs += ... intf_libs = $cxx.deduplicate_export_libs($intf_libs)
