Configure fixes

Packages (ctetgen in particular should not use self.installDirProvider.installSudo directly)

Check that user has write permission on --package-prefix-hash otherwise generate very useful error message

When checking write permission for --prefix print the errors that appear so one has a better understanding of why the permissions are not available

Fix move_configure_log() it did not create one of the intermediate directories and hence would crash if used

Features for Cray KNL systems

Detect Cray compilers and use them automatically, no longer need to use --with-cc=cc etc.
more installation.html information on using theta
Detect MKLROOT and use it if no specific BLAS/LAPACK requested
Error if Cray environment detected but no Cray compiler modules set, prevents compiling with old sequential gnu compilers on the system
For Intel and GNU Cray environments on KNL systems allow compiling packages whose configures call executables by stripping the
KNL specific arguments from the compile libraries for the external libraries, thus --download-hdf5 etc work (note this does
not work for the Cray compilers because I could not figure out how to run the drive.cc programs that the cc compiler
lists when generating the complete compile/link list of compiler arguments, includes, and libraries)

Minor updates based on comments of the reviewers of the MR

Add self.installwithbatch = 0 for hypre since it attempts to run programs during configure
Note that with the PETSc automatic cross compiling on Theta hypre will configure and build successfully

Fix directory for checking default BLAS/LAPACK locations before checking MKLROOT variable

Fixed error in BlasLapack.py which resulted from bad merge and the variables were set too late, changed used of ls to Python function

Many fixes to get PETSc and --download-fblaslapack working with nagfor compiler

Works with --download-fblaslapack, --download-scalapack, --download-mpich (does not work with --download-mumps)

Uses lib/petsc/bin/petscnagfor as wrapper compiler since nagfor cannot work natively with the PETSc/standard Unix build environment

Required fixes/modernizations for BLAS/LAPACK source code (updated in the branch used by this branch, need to make it a tag when done)

Found a couple of portability issues with PETSc mpif.h

When package build fails they will no longer dump all the (huge amount) build output to the screeen
