Robert Yang - Dec. 17, 2013, 11:33 a.m.
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.

[YOCTO #5657]
