# For inclusion in toplevel Makefile
#   Defines some useful macros and variables for building etc
#   If arguments are expected (macro) it needs to be invoked with $(call ...),
#   if no arguments are supported the definition is aregular avariable and can be used as such.
#   Special macros of the name TR_... create targets (and always take arguments)
#   and thus also need to be $(eval ...)'ed
