tracing: Only print objcopy version warning once from recordmcount
If the user has an older version of objcopy, that can not handle converting local symbols to global and vice versa, then some functions will not be part of the dynamic function tracer. The current code in recordmcount.pl will print a warning in this case. Unfortunately, there exists lots of files that may have this issue with older objcopys and this will cause a warning for every file compiled with this issue. This patch solves this overwhelming output by creating a .tmp_quiet_recordmcount file on the first instance the warning is encountered. The warning will not print if this file exists. The temp file is deleted at the beginning of the compile to ensure that the warning will happen once again on new compiles (because the issue is still present).
