Fix lang/gcc-aux

1) Fix NetBSD64, __socket30 compatibility warning
2) Split test target into 5 individual targets that can run individual
   language tests in addition to a chain of 5.
Last minute DESCR change of lang/gcc-aux
Import very old version of florist
Update CVSID of gcc-aux
Add new florist package (3.15p -> GPL 2012)
Proposed fix to maintain precision for Ada and c/c++ long double

Currently being tested, confirmed built as desired.
Changes in gcc-aux diff files resulting from precision update
Remove "UNSUPPORTED" from 16 large type tests in Fortran

Due to the configuration of FPU rounding, the fortran tests were failing
and I thought it was really expected on the *BSD platforms.  However, this
was wrong.  After fixing the FPU settings, they starting passing
"unexpectedly".  Remove the XFAIL designation from these 2 test files.
Set 2 tests as "UNSUPPORTED", unexpected warning free

This is due to long double mantissa rounding to 53 bits on i386.
Disables i386 FreeBSD and i386 DragonFly

(untested so far)
Re-add fortran large real kind modifications -

It passes on i386 but fails on x86_64 due to use of long double
functions not in the math library.
The kind2 fails completely but kind3 only fails without optimization
(Optimization level zero)
Fix gcc.dg/format testsuite

DragonFly already has a quad_t type defined, and it was clashing with
the gcc testsuite, format section, for a lot of false negatives.
Fix testsuite and 2nd build

1) If gnat-aux was installed, 2nd build of gcc-aux would fail due to
path order.
2) Wconversion dejagnu handling had to be fixed, first version failed.
   Now it just checks target and assumes large long doubles capable
3) Tweak of largefiles test to avoid checking for non-existant assy file
Sync FreeBSD/GnatPython
Sync FreeBSD/GPS
Sync FreeBSD/XMLAda
Sync FreeBSD/GTKada
Sync FreeBSD/Gnat-Aux
Sync FreeBSD/GnatDroid (All)
Remove poisoned stack protect routine from freebsd.h

GCC finally standardized this and now freebsd has it by default as
well as NetBSD and OpenBSD.
FreeBSD/lang/gcc-aux: Work in progress (mature)

This builds -- currently undergoing testing.
Seems confirmed that thread abort is still a problem (tasking fails)
plist still needs checking, especially for NLS.
