[distcc] HOWTO rpm/rpmbuild + distcc + ccache?

This seems to be working for me.

vi ~/.rpmmacros

Add to it

%_smp_mflags -j5
%configure \
  CFLAGS="${CFLAGS:-%optflags}" ; export CFLAGS ; \
  CXXFLAGS="${CXXFLAGS:-%optflags}" ; export CXXFLAGS ; \
  FFLAGS="${FFLAGS:-%optflags}" ; export FFLAGS ; \
  CCACHE_DISTCC=1; export CCACHE_DISTCC ; \
  DISTCC_HOST="host1 host2 host3 host4" ; export DISTCC_HOST ; \
  CC="ccache" ; export CC ; \
  CXX="ccache" ; export CXX ; \
  MAKEOPTS="%{_smp_mflags}" ; export MAKEOPTS ; \
  ./configure \\\
        %{?_gnu: --target=%{_target_platform}} \\\
        %{!?_gnu: --target=%{_target_platform}} \\\
        --prefix=%{_prefix} \\\
        --exec-prefix=%{_exec_prefix} \\\
        --bindir=%{_bindir} \\\
        --sbindir=%{_sbindir} \\\
        --sysconfdir=%{_sysconfdir} \\\
        --datadir=%{_datadir} \\\
        --includedir=%{_includedir} \\\
        --libdir=%{_libdir} \\\
        --libexecdir=%{_libexecdir} \\\
        --localstatedir=%{_localstatedir} \\\
        --sharedstatedir=%{_sharedstatedir} \\\
        --mandir=%{_mandir} \\\
        --infodir=%{_infodir}

Since many of the more modern .spec files using %configure, this will setup
everything for ccache and distcc.

Make sure you change DISTCC_HOST to your hostname.
Change _smp_mflags to whatever -j you want passed to make.
