Unless you are cross-building, no.

It means your libc does not supply the specific GNU atomics __sync_*()
API Squid makes use of. Note that is different from pthreads, general
"atomic support" or even C++11 atomics.


For cross-building it is:
  ./configure squid_cv_gnu_atomics=yes ...

but only use that if you are certain the target machine libc has the
right API available *and working*. Otherwise all you are doing is
building a Squid binary that will corrupt the shared memory it uses.
