New description:
Some components of Sage, e.g., libsingular, link in the systemwide
libtermcap.so dynamically instead of statically linking the libtermcap.a
that is built by the Sage termcap spkg. This is a *big problem* when
building a binary on a system that has libtermcap.so and trying to run it
on another system that does not have that so.
Solution?: Modifying the spkg-install script for termcap so it also builds
the so libraries.
* See also #12725, which changes the termcap spkg...

Comment (by jdemeyer):
The version of termcap in Sage (i.e. the official upstream version) does
not support building shared libraries. So, I am a bit surprised to see
the file `libtermcap.so` appear on your system. Could you try whether the
spkg from #12725 fixes the problem? i.e. build termcap from #12725 and
then rebuild Singular and check whether `local/lib/libsingular.so` still
links against `libtermcap.so`
