anjiahao d5981375a6 Support gcc FORTIFY_SOURCE features for nuttx libc 
This function will use gcc's function
__builtin_dynamic_object_size and __builtin_object_size

Its function is to obtain the size of the object through compilation,
so as to judge whether there are out-of-bounds operations in commonly used functions.
It should be noted that the option -O2 and above is required to enable this function

re-calculating the buffer size.

Gregory Nutt 2ccc0da0c7 Move getopt() variables into TLS 
getopt() in the FLAT build environment is not thread safe.  This is because global variables that are process-specific in Unix are truly global in the FLAT build.  Moving the getopt() variables into TLS resolves this issue.

No side-effects are expected other than to getopt()
