---Problem Description---
[Ubuntu 22.04] smc_run does not work, libsmc-preload.so cannot be preloaded
===========================================================================
The reason for this is that the aforementioned shared object is
installed under: /usr/lib64/libsmc-preload.so
Which is AFAICT not what we want, because AFAIU it violates the Debian
Policy Manual (https://www.debian.org/doc/debian-policy/ch-
opersys.html#s-fhs), and ld.so in Ubuntu has a default search path
that understandably does not cover /usr/lib64.
Interestingly the upstream Make file does try to detect if we are run
on Ubuntu, and choose the install path accordingly.
Hereby it relies on "lsb_release -si" returning "Ubuntu", which may or
may not be a good idea -- I don't know.
In any case if the upstream Makefile does not suit Ubuntu/Debian, then
the packager is ought to patch it.
Thus in my opinion this is a packaging problem.

---Steps to Reproduce---
$ smc_run ping 172.18.39.17
ERROR: ld.so: object 'libsmc-preload.so' from LD_PRELOAD cannot be preloaded
(cannot open shared object file): ignored.
PING 172.18.39.17 (172.18.39.17) 56(84) bytes of data.
BTW
$ LD_PRELOAD=libsmc-preload.so LD_DEBUG=libs LD_LIBRARY_PATH=/usr/lib64/ ping
172.18.39.17
does work as expected.
