Subject: [PATCH] gcc-pass2: Fix description of LDFLAGS_FOR_TARGET=

Pass 2 libstdc++ still links to libgcc.a even with LDFLAGS_FOR_TARGET=,
despite this libgcc.a is from pass 2 instead of pass 1.

The difference between pass 2 libgcc and pass 1 libgcc is Glibc wasn't
installed when the pass 1 libgcc was built.  This difference causes both
consequences (1) pass 1 libgcc lacks shared library and (2) pass 1
libgcc cannot support C++ EH, but it's not (1) causing (2).
