Usage: $1 <options>

Options are:
* --cflags  : outputs the compiler flags on stdout
* --lib     : ouputs only the library link flag (not all the -nodefaultlibs... options
* --ldflags : outputs only the link flags (and not the -lrflpc17xx)
* --libs    : concantenation of --lib and --ldflags
* --libfile : outputs the full path of the library file
* --objs    : ouput only object files names. This can be used for project where the main is defined in a library. This will allow library cyclic dependencies to be resolved correctly

If the file $CONFIG_FILE is empty or missing, a minimal library configuration is used.
If the file $CONFIG_FILE does not define a platform to use, MBED is used as default
