[BZ #16195] Fix build warnings from systemtap probes in non-systemtap configurations
Joseph pointed out in the bug report (and in an earlier thread) that systemtap probes cause build time warnings like the following: ../sysdeps/ieee754/dbl-64/e_atan2.c:602:4: warning: the address of 'p' will always evaluate as 'true' [-Waddress] due to the fact that we're now passing non-weak variables to LIBC_PROBE in the libm probes. This happens only on configurations that do not enable systemtap. The macro definition of LIBC_PROBE in this case only acts as a sanity checker to ensure that the number parameters passed to LIBC_PROBE is equal to the argument count parameter passed before it. This can be done in a much simpler manner by just adding a macro definition for each number of arguments. I am assuming here that we don't really want to bother with supporting LIBC_PROBE with an indeterminate number of arguments and if there is a need for a probe to have more data than what is currently supported (4 arguments), one could simply add an additional macro here.
