Subject: gcc: Disable use of sdt.h header

The target sysroot might contain sdt.h but we don't list this in DEPENDS
and shouldn't be referencing it. Unfortunately there is no way to tell
configure this since these tests are uncached and we can't force
a particular value. The only option is therefore to patch this out.

+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.
