Would this by any chance be places where libtool is being used to build
static and shared libraries?
libtool, when building the same file twice with different PIC options,
redirects stdout and stderr to /dev/null for the second build, under the
assumption that the compiler warning output the second time will be
identical to the first and there's no reason to repeat it.
