Subject: [PATCH] For C++ programs, don't emit any explicit dependency to
 libstdc++.a or libc++.a during the early build stages (bootstrap-tools,
 build-tools, cross-tools), since it is not possible to know in advance which
 C++ library is available on the host system.

Instead, just use the bootstrap compiler's built-in default.  This
should eventually make it possible to build stable/9 on head, or on
stable/10, which ship without libstdc++ by default.
