Allows us to use the built-in suffix rules where appropriate.
FORTRAN -> FC (POSIX)
OPTS -> FFLAGS (POSIX)
DRVOPTS -> FFLAGS_DRV
NOOPT -> FFLAGS_NOOPT
LOADER -> FC (use the compiler driver for linking)
LOADOPTS -> LDFLAGS (POSIX)
ARCH -> AR (POSIX)
ARCHFLAGS -> ARFLAGS (POSIX)
Added ilaenv2stage.f to enable the extraction of 2stage machine dependent
variables from the 2stage solver without having to rely on compiling the
entire library with the recursive flag.
Secondly, all calls to ILAENV( 17 <= 21, ...) have been fixed to
use the corresponding ILAENV2STAGE routine by translating ISPEC by -16
I.e.
ILAENV( 17, ...) == ILAENV2STAGE( 1, ...)
Also fixed the documentation of ilaenv.f to specify the cases of ISPEC > 16.

Adds LAPACKE_WITH_TMG to make.inc.example, adds BUILD_DEPRECATED to
everything in the INSTALL dir.
Sort the variables by programs and their flags, then build options, then
library names.
This is mostly a long term maintenance improvement.
Many coding styles require elimination of trailing whitespace, and
many editors and source code management configurations automatically
gobble up whitespace. When these tools gobble up whitespace, it
complicates reviewing the meaningful code changes.
By removing whitespace on one patch, it makes future
code reviews much easier.

# Note: During a regular execution, LAPACK might create NaN and Inf

They are compiled and included in the liblapack.a archive when
the MAKEDEPRECATED option in the make.inc file is set.
TODO: Add the corresponding behavior to the cmake files.
NOTE: The xGEQPF routines are deprecated but still used by some
non-deprecated routines. They have not been moved to the DEPRECATED
directory.

This is a problem with gfortran. One need to force gfortran to allocate all
local arrays on the stack. One way to do this is to have the option
-frecursive
First commit, works on my mac! Need to see how to adapt to intel compilers and of course Windows.
LAPACKE is not built by default. Is that OK?
User need to type 'make lapackelib' to generate the lib
I add a couple of examples taken from MKL LAPACKE 'make lapacke_example'
Jason (Riedy) wrote our ( ... his? :) ) ideas about it three years ago:
http://www.netlib.org/lapack-dev/lapack-coding/program-style.html#id2537289
Piotr (Luszczek) has written two subroutines, tested them on few platforms, collected the result on his webpage, and sent emails to the lapackers a few times. See:
http://www.cs.utk.edu/~luszczek/lapack/lamch.html
Theses slamch.f and dlamch.f subroutines were taken from PLASMA-2.1.0.
Change to the LAPACK library:
* move the current LAPACK subroutine slamch.f (resp dlamch.f) as
slamchf77.f (resp. dlamchf77.f),
* take the new slamch.f subroutines (resp. dlamch.f), remove the PLASMA
header, have a LAPACK header, and insert the new routines in the
library.
Minor:
* I would leave these routines compiled with the NOOPT flag.
Problem:
* CLAPACK: no idea how CLAPACK's going to handle this. CLAPACK can rely on
IEEE arithmetic, can relay on float.h, or can rely on the previous
xlamch.f
