Gerald Pfeifer f4ecd3423a Update to the 20130831 snapshot of GCC 4.7.4.
Work around a bug in libcpp that pulls in the optional system iconv
if present instead of relying on the port we actually depend on. [1]

The issue is that /usr/include/iconv.h has #include <stdbool.h> which
in turn, since both are included very late in the game, conflicts with
similar definintions by libcpp itself.

Interestingly enough, lang/gcc46 and lang/gcc48 did not fail under the
same test scenarios and libstdc++ does not seem to require adjustments,
so PR 161417 may not be relevant in full.
