Sorry, I misread (went for the Documentation instead of getting the version 
from the toolchain). My bad

I do not use any specific features coming with RTEMS 5

I checked again the effective version of the toolchain, and it is: 
sparc-gaisler-rtems4.12-gcc (Cobham Gaisler RCC 1.3-rc2) 7.2.0

Are the Gaisler tools also version RTEMS 5.0?

The version I am seeing on my machines is:

gcc version 7.2.0 20170814 (RTEMS 5, RSB 
089327b5dcf944bfc1d8d7f1ad1d30330088da72, Newlib 2.5.0.20170922) (GCC)

You need to use tools built for 5 with RTEMS 5. There are a number of newlib 
changes the kernel depends on.
