# USAGE:
# Variables that must be defined in including makefile.
#   PROJECT: Name to be given to the output binary for this project.
#   SRC: The root directory for the sources of your project.
#   GCC4MED_DIR: The root directory for where the gcc4mbed sources are located
#                in your project.  This should point to the parent directory
#                of the build directory which contains this gcc4mbed.mk file.
#   LIBS_PREFIX: List of library/object files to prepend to mbed.ar capi.ar libs.
#   LIBS_SUFFIX: List of library/object files to append to mbed.ar capi.ar libs.
#   GCC4MBED_TYPE: Type of build to produce.  Allowed values are:
#                  Debug - Build for debugging.  Disables optimizations and
#                          links in debug MRI runtime.  Best debugging
#                          experience.
#                  Release - Build for release with no debug support.
#                  Checked - Release build with debug support.  Due to
#                            optimizations, debug experience won't be as good
#                            as Debug but might be needed when bugs don't
#                            reproduce in Debug builds.
#                  default: Release
#   MRI_BREAK_ON_INIT: Should the program halt before calling into main(),
#                      allowing the developer time to set breakpoints in main()
#                      or in code run from within global constructors.
#                      default: 1 - break on init.
#   MRI_SEMIHOST_STDIO: Set to non-zero value to allow debug monitor to use
#                       semi-host calls to redirect stdin/stdout/stderr to the
#                       gdb console.
#                       default: 1 for Debug/Checked builds and 0 for Release.
#   MRI_UART: Select the UART to be used by the debugger.  See mri.h for
#             allowed values.
#             default: MRI_UART_MBED_USB - Use USB based UART on the mbed.
