           Summary: [4.6 Regression] plugin linker is used unconditionally
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rguenth@gcc.gnu.org
                CC: hubicka@gcc.gnu.org


We now seem to always pass -plugin ./liblto_plugin.so ... to collect2, even
when not using LTO.  This causes us to always use the linker configured
for plugin use (--with-plugin-ld) via the collect-ld script and thus
with --with-plugin-ld=gold gold will be always used (which breaks the build
of libgo for me as gold is too old appearantly).

int main() { return 0; }
