Subject: [PATCH] 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.
