[ Upstream commit fe4d0d5dde ]
Linus had a problem compiling RTLA, saying:
"[...] I wish the tracing tools would do a bit more package
checking and helpful error messages too, rather than just
fail with:
fatal error: tracefs.h: No such file or directory"
Which is indeed not a helpful message. Update the Makefile, adding
proper checks for the dependencies, with useful information about
how to resolve possible problems.
For example, the previous error is now reported as:
$ make
********************************************
** NOTICE: libtracefs version 1.3 or higher not found
**
** Consider installing the latest libtracefs from your
** distribution, e.g., 'dnf install libtracefs' on Fedora,
** or from source:
**
** https://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git/
**
********************************************
These messages are inspired by the ones used on trace-cmd, as suggested
by Stevel Rostedt.

Changes from V1:
- Moved the rst2man check to the install phase (when it is used).
- Removed the procps-ng lib check [1] as it is being removed.
