Why -nodefaultlibs -nostdlib used in project example Tx_MPU

[Mark Hadden]

My project requires the use of Threadx Modules. Using the TX_MPU example as a guide I have successfully created a Module with some basic functionality using Queues, Mutex and byte pools.
Looking in the Makefile I noticed that -nodefaultlibs and -nostdlib settings are used.
Is there a specific reason why theses settings are used for the Module build? Does it mean that default and standard libraries can not be used by code in the Module?
