remove JIT compiler from Octave sources
As stated in the NEWS file entry added with this changeset, no one
has ever seriously taken on further development of the JIT compiler in
Octave since it was first added as part of a Google Summer of Code
project in 2012 and it still does nothing significant. It is out of
date with the default interpreter that walks the parse tree. Even
though we have fixed the configure script to disable it by default,
people still ask questions about how to build it, but it doesn’t seem
that they are doing that to work on it but because they think it will
make Octave code run faster (it never did, except for some extremely
simple bits of code as examples for demonstration purposes only).

# =========================================================================== # https://www.gnu.org/software/autoconf-archive/ax_lapack.html # =========================================================================== # # SYNOPSIS # # AX_LAPACK([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]) # # DESCRIPTION # # This macro looks for a library that implements the LAPACK linear-algebra # interface (see http://www.netlib.org/lapack/). On success, it sets the # LAPACK_LIBS output variable to hold the requisite library linkages. # # To link with LAPACK, you should link with: # # $LAPACK_LIBS $BLAS_LIBS $LIBS $FLIBS # # in that order. BLAS_LIBS is the output variable of the AX_BLAS macro, # called automatically. FLIBS is the output variable of the # AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is # sometimes necessary in order to link with F77 libraries. Users will also # need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same # reason. # # The user may also use --with-lapack=<lib> in order to use some specific # LAPACK library <lib>. In order to link successfully, however, be aware # that you will probably need to use the same Fortran compiler (which can # be set via the F77 env. var.) as was used to compile the LAPACK and BLAS # libraries. # # ACTION-IF-FOUND is a list of shell commands to run if a LAPACK library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_LAPACK. # # LICENSE # # Copyright (c) 2009 Steven G.
