We see the following error when using "real (kind=16)" with gfortran version coming from devtoolset 2:

$ gfortran /tmp/kul.f90 
/tmp/ccg1VSEr.o: In function `MAIN__':
kul.f:(.text+0x67): undefined reference to `_gfortran_transfer_real128_write'
collect2: error: ld returned 1 exit status

$ cat /tmp/kul.f90 
       program main
       implicit none
       real ( kind=16 ) x
       x = 1.0
       write (*,*) x
       end
