Libatomic and libgnat from gcc-4.8.5-4 appear not to be built on
aarch64. How to file bug? See below from spec:
Summary: Various compilers (C, C++, Objective-C, Java, ...)
Name: gcc
%if 0%{?rhel} == 7
%global gcc_version 4.8.2
%else
%global gcc_version 4.8.5
%endif
Version: 4.8.5
Release: %{gcc_release}%{?dist}

( Missing aarch64 )
v
%ifarch %{ix86} x86_64 ppc ppc64 ppc64le ppc64p7 s390 s390x aarch64 %{arm}
%global build_libatomic 1
I did a smoke test and was able to bootstrap both using f21 aarch64.
Have the rpms if needed.
