fix: support new trace compiler features for preventing clashes. Automatically turn on OST_TRACE_COMPILER_IN_USE macro. Look for trace header in systemincludes. Make directories in makefile parse to prevent clashes during build. Correct path for autogen headers. Correct case issue with autogen headers on Linux.

# Description: 
# Generate some useful statistics from a Raptor build log
# Work out what was specified to make but not built even if
# it was not mentioned in the make error output because some
# child's dependency was not satisfied.
# Needs raptor --tracking option to set make to use -debug=v
# An example bit of make output that can be analysed:
#
