I tried to update the RTEMS 6/7 tools yesterday and all builds failed on 
my FreeBSD machine. The reason is this change in GDB:

     gdb: Make GMP a required dependency for building GDB

     This commit modifies gdb's configure script to trigger an error
     if we cannot find a usable libgmp.

     For the record, making this a requirement was discussed in March 2018:


             * Generate an error if a usable GMP library
             could not be found.
             * configure: Regenerate.

The GMP library is not available by default on FreeBSD systems. For GCC 
we include a fixed version and build it together with GCC. What should 
be do for GDB?
