This followup to PR modula2/122241 reduces error message clutter by
filtering unknown symbol error ensuring that only one error message
is emitted for an unknown symbol at a particular location.
The filter is implemented using two binary trees.  A new generic
(based on the address type) binary dictionary module is added to
the base libraries.

The new wideset implementation uses an ARRAY OF BYTE (internally) to
represent large sets.  This replaces the huge struct of anonymous
fields created by the old implementation and results in quicker
declaration times for large set types.

This patch introduces a Write procedure for an array of char,
the string and char datatype.  It uses the m2r10 style of
naming the module on the datatype.  This uncovered a bug
in the import handling inside Quadident.  It also includes
an Unlink procedure from a new module FileSysOp and a String
interface to this module.

This patch corrects commit
r14-4149-g81d5ca0b9b8431f1bd7a5ec8a2c94f04bb0cf032 which assummed
all powerpc platforms would have IEEE754 long double.  The patch
ensures that cc1gm2 obtains the default IEEE754 long double availability
from the configure generated tm_defines.  The user command
line switches -mabi=ibmlongdouble and -mabi=ieeelongdouble are implemented
to override the configuration defaults.

Bootstrapped on power8 and power9 machines.

Recent Darwin versions place contraints on the use of run paths
specified in environment variables.  This breaks some assumptions
in the GCC build.

This change allows the user to configure a Darwin build to use
'@rpath/libraryname.dylib' in library names and then to add an
embedded runpath to executables (and libraries with dependents).

The embedded runpath is added by default unless the user adds
'-nodefaultrpaths' to the link line.

For an installed compiler, it means that any executable built with
that compiler will reference the runtimes installed with the
compiler (equivalent to hard-coding the library path into the name
of the library).

During build-time configurations  any "-B" entries will be added to
the runpath thus the newly-built libraries will be found by exes.

Since the install name is set in libtool, that decision needs to be
available here (but might also cause dependent ones in Makefiles,
so we need to export a conditional).

This facility is not available for Darwin 8 or earlier, however the
existing environment variable runpath does work there.

We default this on for systems where the external DYLD_LIBRARY_PATH
does not work and off for Darwin 8 or earlier.  For systems that can
use either method, if the value is unset, we use the default (which
is currently DYLD_LIBRARY_PATH).

ChangeLog:

	* configure: Regenerate.
	* configure.ac: Do not add default runpaths to GCC exes
	when we are building -static-libstdc++/-static-libgcc (the
	default).
	* libtool.m4: Add 'enable-darwin-at-runpath'.  Act  on the
	enable flag to alter Darwin libraries to use @rpath names.
