The tkr m4's fortran couldn't be compiled
by gfortran. pointer assignment followed by
variabl definition didn't compile.

The Intel 2016 compiler suite apparently only partially supports the
!GCC pragmas (prior versions either didn't support it at all, or our
existing configure test was sufficient to disqualify !GCC pragma
support when compiling with the Intel compiler).
With the existing configure test, the Intel 2016 compiler suite would
*pass* the test and therefore think that it could use !GCC as the
"ignore TKR" pragma. However, the "!GCC ATTRIBUTES NO_ARG_CHECK"
pragma doesn't work with scalar integers (although it seems to work
for the other types in this test).
This commit adds a scalar integer test to the ignore TKR pragma
configure test, which is enough to make the Intel 2016 compiler suite
fail with !GCC (this then allows configure to advance on to trying the
!DEC pragma, which *does* work properly with the Intel 2016 compiler
suite).
Thanks to Fabrice Roy for reporting the problem.

upcoming GCC/gfortran 4.9's ignore TKR interface.
This was originally committed in a side mercurial repo, but I sadly
completely forgot about it until Tobias reminded me.

config/ directory. We split them apart a while ago in the hopes that
it would simplify things, but it didn't really (e.g., because there
were still some ompi/opal .m4 files in the top-level config/
directory, resulting in developer confusion where any given m4 macro
was defined).
So this commit consolidates them back into the top-level directory for
simplicity.
There's still (at least) two changes that would be nice to make:
1. Split any generated .m4 file (e.g., autogen-generated .m4 files)
into a separate directory somewhere so that a top-level -Iconfig/
will only get our explicitly defined macros, not the autogen stuff
(e.g., with libevent2019 needing to get the visibility macro, but
NOT all the autogen-generated inclusion of component configure.m4
files).
1. Change configure to be of the form:
{{{
# ...a small amount of preamble/setup...
OPAL_SETUP
m4_ifdef([project_orte], [ORTE_SETUP])
m4_ifdef([project_ompi], [OMPI_SETUP])
# ...a small amount of finishing stuff...
}}}
I doubt we'll ever get anything as clean as that, but that would be
the goal to shoot for.
