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.

kbuild: rename ld-option to cc-ldoption2009-09-20T10:27:42ZSam Ravnborg2009-09-19T08:14:33Zurn:sha1:f86fd306605287d7c7f4f0f8e8e2a9d49d28b396
ld-option is misnamed as it test options to gcc, not to ld.
Renamed it to reflect this.
