Use C++ test case with exceptions and std to see if C++ libraries are needed explicitly when
linking with C/Fortran. Just having a C++ main isn't a comprehensive test.

Therefore test it can handle this, if not configure must autogenerate the need

Generate C, Fortran, and C++ library lists only if needed for linking
Before generating language lists try linking with other linkers and
see if the linking suceeds without the library lists; only if the link
fails does it generate the explicit library lists.
This should eliminate the need for the usage of
'--with-clib-autodetect=0',
'--with-cxxlib-autodetect=0',
'--with-fortranlib-autodetect=0',
on Cray systems.

Auto detect if the BLAS/LAPACk use 32 or 64 bit integers.
In batch mode user MUST provide this information, also changed checks for sdot and snrm returning double to not use batch program
because the checks could crash the batch program. Hence
in batch mode users must always provide
