From 6573aec00ada35c48c1838c8491ce8f7798ae993 Mon Sep 17 00:00:00 2001

Subject: [PATCH 23/46] 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.

Disable sdt for libstdc++-v3.
