[S390] vdso: disable gcov profiling
The concepts of VDSO and gcov-based profiling don't mix: the former includes kernel-provided code running in userspace, the latter adds instructions that modify counters in kernel data segments. On s390 this has not been a problem so far due to VDSO code being written in all-assembler which is exempt from gcov-based profiling. This could change in the future, so disable profiling excplicitly for VDSO code.
