gcda files

Hi, I use a cross compiler using a cross compiler (--build=x86_64-suse-linux --host=x86_64-suse-linux --target=aarch64_be-linux-gnu) gcov-tool to merge tree profiles generated by big endian machine. 
gcov-tool merge dir1 dir2 -o dir12
gcov-tool merge dir3 dir12 -o dir123

I am confronted with "./main.gcda:incorrect gcov version xxxxxx vs yyyyyyy" error.

known to fail on all active branches.
