This is useful to see if, on x86, the legacy libaudit still works, as it
is used in architectures that don't have the SYSCALL_TABLE logic and we
want to have it tested in 'make -C tools/perf/ build-test'.
E.g.:
Without having audit-libs-devel installed:
$ make NO_SYSCALL_TABLE=1 O=/tmp/build/perf -C tools/perf install-bin
make: Entering directory '/home/acme/git/perf/tools/perf'
BUILD: Doing 'make -j12' parallel build
<SNIP>
Auto-detecting system features:
<SNIP>
... libaudit: [ OFF ]
... libbfd: [ on ]
... libcap: [ on ]
<SNIP>
Makefile.config:664: No libaudit.h found, disables 'trace' tool, please install audit-libs-devel or libaudit-dev
<SNIP>
After installing it:
$ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf
$ time make NO_SYSCALL_TABLE=1 O=/tmp/build/perf -C tools/perf install-bin ; perf test python
make: Entering directory '/home/acme/git/perf/tools/perf'
BUILD: Doing 'make -j12' parallel build
HOSTCC /tmp/build/perf/fixdep.o
HOSTLD /tmp/build/perf/fixdep-in.o
