[PATCH 1/2] gcc-4.8/libstdc++-v3: disable sdt

[Robert Yang]

We may meet such an error when building gcc/libstdc++-v3:

gcc-4.8.1/libstdc++-v3/libsupc++/unwind-cxx.h:41:21: fatal error:
sys/sdt.h: No such file or directory

We already have a patch to disable the sdt for gcc, we also need disable
it for libstdc++-v3.

BTW, we need edit both configure.ac and configure to make them keep
compatible.

NOTE, this commit edit the patch gcc-4.8/0031-Disable-sdt.patch directly.

[PATCH 2/2] gcc-4.7/gcc: disable sdt from configure.ac to keep compatibility with configure

[Robert Yang]

We had disabled the sdt from configure, let's also disable it from
confgure.ac to keep them compatible.

BTW, the libstdc++-v3 of gcc-4.7 doesn't use the sdt, so we don't need
to edit libstdc++-v3/configure as gcc-4.8.

NOTE, this commit edit the patch gcc-4.7/disablesdt.patch directly.
