From: Hendrik Brueckner <brueckner@xxxxxxxxxxxxxxxxxx> Change the Makefile and build process to no longer require audit-libs interfaces when the architecture provides system call tables. Committer notes: Its not enough to hook into the NO_LIBAUDIT makefile block, we need to define a CONFIG_TRACE that gets selected by both architectures generating the syscall tables from the kernel headers and from detecting the availability of libaudit. With that in place we will not link against libaudit even if the necessary files are available for that, in fact we will not even try to detect its availability, speeding up a bit the feature detection phase.
