No change with 3.6.0-2.

No, it isn't. #810143 is about removed symbols, but here we have newly
added symbols in /usr/lib/lapack/liblapack.so.3 that are used by
liblapacke.so.3

But molds explicitly links (and sets a rpath) against
/usr/lib/openblas-base/liblapack.so.3 which does not have these new symbols:

mpicxx -o molds -Wl,-rpath=/usr//lib/ -Wl,-rpath=/usr/lib/openblas-base
$LISTOFOBJECTFILES
-L/usr//lib/ -L/usr/lib/openblas-base -lstdc++ -lm -lpthread -lgomp
-L/usr/lib/lapack/ -llapacke -lmpi -lmpi_cxx -lboost_serialization
-lboost_mpi -lboost_thread -lboost_system -lopenblas

Introducing new public symbols in /usr/lib/lapack/liblapack.so.3 was
probably not a good idea since liblapack.so.3 is managed by alternatives.
