This should make it easier to compile ELPA for Debian/Ubuntu, now it
should be sufficient to just

  ./configure

without a need to set LIBS or SCALAPACK_LDFLAGS

Automake does not easily allow to use the same source in a libtool
library and in a program

In case of SSE/AVX/AVX2 it could happen that more than one kernel
(since some depend on other kernels, e.g. block 6 on block 4 and
block 2) were called

The issue why these test programs are simply not build
has to be investigated

Test

-with/without mpi
-with/without openmp
-with/without ftimings
-with/without redirect

all kernels
