A later linker CL defines a function that needs to forward a printf format and argument list to TRACE(), but there is no version of the TRACE macro that works with a va_list. The CL also needs to check the verbosity level, using a slow path if tracing is enabled, so define LINKER_VERBOSITY_xxx macros. Bug: none Test: bionic unit tests Change-Id: I578d36a12dc40f9a651956b4b09adc1a7c644e24
