Debug Information
For dev builds we split debug information using split-debuginfo="packed",
which seems to speed up linking time and the resulting binaries are not
distributed anyway. For release builds we enable debug = "line-tables-only"
to enable line and function information in backtraces. In the mcrl2 tools we
do not split debug info since cpptrace cannot seem to find it, and this breaks
stack traces in the C++ code.
