Description of problem:

I try to compile devtoolset-4-gcc without scl on a fresh installed CentOS 6.7 x86_64, with `Name:' switched to `Name: %{?scl_prefix}gcc%{!?scl:5}', but encounter 2 problems:

1. libmpxwrapper is not compiled.
2. /usr/bin/gcov-tool is not renamed to /usr/bin/gconv-tool5

The first problem is due to lack of support of MPX in binutils.  After I upgrade binutils to 2.25.1, libmpxwrapper gets compiled.

The second problem is due to the line in gcc.spec doesn't include the new added `gcov-tool':

%if 0%{!?scl:1}
for i in %{buildroot}%{_prefix}/bin/{*gcc,*++,gcov,gfortran,gcc-ar,gcc-nm,gcc-ranlib}; do
  mv -f $i ${i}5
done
%endif

Version-Release number of selected component (if applicable):
devtoolset-4-gcc-5.2.1-2.2.el6

How reproducible:
Always.

Steps to Reproduce:
1. Edit gcc.spec, switch `Name:' to `Name: %{?scl_prefix}gcc%{!?scl:5}'
2. rpmbuild -ba gcc.spec
3. Upgrade binutils to 2.23.52.0.1 or up and rpmbuild -ba gcc.spec again

Actual results:
The following line gives `file not found' error:
mv -f %{buildroot}%{_prefix}/%{_lib}/libmpxwrappers.*a $FULLLPATH/

File not found: /root/rpmbuild/BUILDROOT/gcc5-5.2.1-2.2.el6.x86_64/usr/bin/gcov-tool5

Expected results:
Compiled without problem.

Additional info:
Modification of gcc.spec would fix these problems:

1. Rename gcov-tool:
for i in %{buildroot}%{_prefix}/bin/{*gcc,*++,gcov*,gfortran,gcc-ar,gcc-nm,gcc-ranlib}; do
  mv -f $i ${i}5
done

2. BuildRequires: binutils >= 2.23.52.0.1-30
