As far as I can tell, things go wrong in <cstdint> in the "#if
_GLIBCXX_HAVE_STDINT_H" conditional---because if I repeat the above compiler
invocation with -D_GLIBCXX_HAVE_STDINT_H=1, compilation succeeds.
Note that while this system has no stdint.h header under /usr/include/, GCC
does provide one of its own ($(builddir)/gcc/include/stdint.h), and this header
is pulled in when _GLIBCXX_HAVE_STDINT_H is #defined to non-zero (confirmed via
-E).
_GLIBCXX_HAVE_STDINT_H is #undef in the various instances of c++config.h in the
build tree. If I hand-modify these in accordance with the above, the build
proceeds.
I believe the appropriate fix would be to have the libstdc++ configure-time
check for stdint.h regard GCC's header as satisfying the check. (If GCC
provides this header only when the system doesn't have one, or provides it
unconditionally, then perhaps the check is not needed at all.)
