We seldom can reproduce this error, RP had fix this issue for gcc, it seems that we also need the patch for libstdc++-v3:


Subject: [PATCH 31/35] Disable sdt.

We don't list dtrace in DEPENDS so we shouldn't be depending on this header.
It may or may not exist from preivous builds though. To be determinstic, disable
sdt.h usage always. This avoids build failures if the header is removed after configure
but before libgcc is compiled for example.

Will send the patch sooner.
