New Revision: 257658
URL: http://svnweb.freebsd.org/changeset/base/257658
Log:
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.
