Patch needed for GCC 9?

[Joel Sherrill]

Hi

When I build RTEMS with GCC 9 (sparc/leon3) to get Coverity results, I get
this error linking tests that I don't get with gcc 10. I am using the same
newlib and binutils-gdb source so I am a bit confused. Are there patches in
GCC 10 that I need on GCC 9?
