The attached patch solves the bootstrap failures in PR54642 where the
file lto-symtab.o is rebuilt during 'make install' by the system compiler
due to the dangling dependency left on gt-lto-symtab.h for lto-symtab.o.
Tested on x86_64-apple-darwin12 against clang/clang++ of Xcode 4.5.
Okay for gcc trunk?
