libexecdir is GNU Standards for ages (decades).
It's supposed to be kind of an "auxilliary bindir", to hide away
programs, users are not supposed to execute directly.
It's formal definition[1] is
<cite>
libexecdir
The directory for installing executable programs to be run by other
programs rather than by users. This directory should normally be
â/usr/local/libexecâ, but write it as â$(exec_prefix)/libexecâ. (If you
are using Autoconf, write it as â@libexecdir@â.)
The definition of âlibexecdirâ is the same for all packages, so you
should install your data in a subdirectory thereof. Most packages
install their data under â$(libexecdir)/package-name/â, possibly within
additional subdirectories thereof, such as
â$(libexecdir)/package-name/machine/versionâ.
</cite>
In Fedora, we treat libexecdir as optional and allow packages to install
such "non-user programs" to %libdir/<subdir>/ instead, primarily for
historical reasons.

Multilib subdirs are arbitrary directory names. There is no convention
of them being named "lib*".
You might not have tripped over such them on intel based platforms, but
are very common on other architectures/OSes.
