BUILD: Add build infrastructure for systemtap scripts
Adds infrastructure that generatest the probes.h and probes.o from the
dtrace probes.d file. The probes.d file is empty except for the provider
name in this commit, its content will be added with later commits that
actually add some content. The probes.d file is always distributed in
the tarball so that distributions can optionally enable systemtap
support.
The generation is done using the "dtrace" command because the probes.d file
is compatible with the Solaris dtrace format. Please see "man 1 dtrace"
for more information on the dtrace format and the command line tool.
In order to make libtool happy, a fake libtool object is generated. This
hunk was taken from the libvirt code.
The AM_V_GEN macro is used to make the build compatible with the silent
build configuration.
To enable systemtap probing, configure sssd with:
--enable-systemtap
In order to do so, the 'dtrace' command-line utility must be installed.
On Fedora and RHEL, this package is installed as part of the
"systemtap-sdt-devel" package.
You'll also want the 'systemtap' package installed as well as the matching
versions of kernel-devel and kernel-debuginfo on your machine.
