Add support for AOCC & Flang w/ the Autotools (#3674) 
* Adds a config/clang-fflags options file to support Flang
* Corrects missing "-Wl," from linker options in the libtool wrappers
  when using Flang, the MPI Fortran compiler wrappers, and building
  the shared library. This would often result in unrecognized options
  like -soname.
* Enable -nomp w/ Flang to avoid linking to the OpenMPI library.

CMake can build the parallel, shared library w/ Fortran using AOCC
and Flang, so no changes were needed for that build system.

Fixes GitHub issues #3439, #1588, #366, #280

AC_PREREQ([2.71])
## AC_INIT takes the name of the package, the version number, and an
## email address to report bugs. AC_CONFIG_SRCDIR takes a unique file
## as its argument.
##
## NOTE: Do not forget to change the version number here when we do a
## release!!!

## AM_INIT_AUTOMAKE takes a list of options that should be applied to
## every Makefile.am when automake is run.
AM_INIT_AUTOMAKE([foreign subdir-objects])
m4_ifdef([AM_SILENT_RULES], [AM_SILENT_RULES([yes])]) # use silent rules where available - automake 1.11
## AM_MAINTAINER_MODE determines the behavior of "rebuild rules" that contain
## dependencies for Makefile.in files, configure, src/H5config.h, etc. If
## AM_MAINTAINER_MODE is enabled, these files will be rebuilt if out of date.
## When disabled, the autotools build files can get out of sync and the build
## system will not complain or try to regenerate downstream files.
##
## The AM_MAINTAINER_MODE macro also determines whether the
## --(enable|disable)-maintainer-mode configure option is available. When the
## macro is present, with or without a parameter, the option will be added
## to the generated configure script.
##
## In summary:
##
## AM_MAINTAINER_MODE([enable])
## - Build dependencies ON by default
## - Configure option exists
##
## AM_MAINTAINER_MODE([disable])
## - Build dependencies OFF by default
## - Configure option exists
##
## AM_MAINTAINER_MODE
## - Build dependencies OFF by default
## - Configure option exists
##
## No AM_MAINTAINER_MODE macro
## - Build dependencies ON by default
## - No configure option to control build dependencies
##
## The biggest concern for us is that version control systems like git
## usually don't preserve dependencies between timestamps, so the build
## system will often think that upstream build files like Makefile.am are
## dirty and that rebuilding needs to occur when it doesn't. This is a problem
## in release branches where we provide the autotools-generated files. Users
## who don't have autoconf, automake, etc. will then have difficulty building
## release branches checked out from git.
##
## By default, maintainer mode is enabled in development branches and disabled
## in release branches.

## Add POSIX support on Linux systems, so <features.h> defines
## __USE_POSIX, which is required to get the prototype for fdopen
## defined correctly in <stdio.h>.
##
## This flag was removed from h5cc as of 2009-10-17 when it was found
## that the flag broke compiling netCDF-4 code with h5cc, but kept in
## H5_CPPFLAGS because fdopen and HDfdopen fail without it. HDfdopen
## is used only by H5_debug_mask which is used only when debugging in
## H5_init_library (all in H5.c). When the flag was removed this was
## the only compile failure noted.
##
## This was originally defined as _POSIX_SOURCE which was updated to
## _POSIX_C_SOURCE=199506L to expose a greater amount of POSIX
## functionality so clock_gettime and CLOCK_MONOTONIC are defined
## correctly. This was later updated to 200112L so that
## posix_memalign() is visible for the direct VFD code on Linux
## systems. Even later, this was changed to 200809L to support
## pread/pwrite in VFDs.
##
