Remove obsolete rtems_gxx_*() implementation

Browse Source 
GCC versions prior to 6.1 used a RTEMS thread model based on
rtems_gxx_*() functions. GCC version 6.1 or later uses the
self-contained synchronization objects of Newlib <sys/lock.h> for the
RTEMS thread model.

Remove the obsolete implementation.

Close #3143.
