on FreeBSD 10, and amd64 on earlier versions.
SSP_UNSAFE is added to disable in a port if it fails to build, but
this should only be used in rare circumstances such as kernel modules.
Otherwise, the port may just be failing due to lack of respecting
LDFLAGS.
On FreeBSD 10, this uses an ldscript in /usr/lib/libc.so to pull in
libssp_nonshared.a to address issues linking on i386 [1].
On earlier FreeBSD versions the WITH_SSP knob will add -lssp_nonshared
to LDFLAGS on i386. This is not needed on amd64. However, several hundred
ports do not currently respect LDFLAGS, so this support is disabled currently
as it causes build failures if a dependency is looking for the stack_chk
symbols.
Many thanks to jlh@ for this as he had many years of patience in getting
all of the necessary pieces [1][2] in.

exp-runs done: 37 over a month on 91i386,91amd64,10i386,10amd64
heavily inspired by several upstream patches and a crucial hint from tijl.
- Remove a redundant compiler flag for MDDS. The GXX_INCLUDE_PATH variable
was removed with STLport support and it seems it is not necessary any more.
- Add an upstream patch. It may work around a potential compiler problem.
- Convert to new LIB_DEPENDS format.
It's value is "--with-libiconv-prefix=/usr/local" for systems
before 100043 with ports libiconv and to use at systems post
100043 with base iconv it's value is "" (NULL).

after r254273
- Fix a bunch of ports to properly work after this
- Mark converters/libiconv as IGNORE for systems with iconv in libc

Discussed with: bapt, bsam (who both contributed ideas and code)
1) Move -a from XMKMF command variable to a new XMKMF_ARGS variable.
For ports that don't need -a introduce USES=imake:notall.
This way ports no longer have to redefine XMKMF.
2) xmkmf -a runs imake with the flags in IMAKECPPFLAGS as extra arguments
to set CPP, CC and CXX. This creates the top Makefile, and then xmkmf
runs make Makefiles. This Makefiles target runs imake for each
subdirectory but these imake invocations did not have the flags from
IMAKECPPFLAGS so the resulting makefiles used the wrong C preprocessor
when clang is used (/usr/bin/cpp instead of /usr/local/bin/tradcpp).
Instead of letting xmkmf pass IMAKECPPFLAGS from the environment to
imake let imake handle IMAKECPPFLAGS itself just like it handles
IMAKEINCLUDE.
This exposed configure errors in x11-clocks/mouseclock and x11-wm/fvwm.

Update dependent packages with more recent releases.
Remove old and bit-rotted ones.
Switch to using clang 3.3 and libobjc2 1.7 by default, so modern Objective-C features work out of the box and remove a lot of configurable options for sub-optimal (and, often, unsupported / deprecated upstream) configurations.
Take maintainership of GNUstep-related ports.
Several of the ports left in have scary warnings which mean that they are likely broken in lots of cases. Future commits will fix them.
