[toolchain] gcc: remove support for 4.7.0 

There are no good reasons for keeping this version around when 4.7.2 and
4.7-linaro are there.

Signed-off-by: Florian Fainelli <florian@openwrt.org>

There is one usage in boehm-gc/os_dep.c, but it is only used if
SUNOS5SIGS is defined, which it is only if one of SUNOS5, DRSNX, HPUX, or
FREEBSD is defined, which are all not using Linux-based glibc ports.
Likewise, gcc/ada/init.c has a struct __siginfo occurence, but only for
__FreeBSD__.
config/rs6000/linux-unwind.h uses ``char siginfo[128]'', and
config/s390/linux-unwind.h also uses a constant.
I tested the following patch for sh-linux-gnu. This only covers one
configuration, but the change is pretty mechanic anyway and every place
that used to refer to struct siginfo already must have had <signal.h> in
its include path, which is the same file that declares siginfo_t.
OK to commit? This should probably also go into any active release
branches, to keep them buildable once this glibc change ripples through?

This patch brings over a few features from MirBSD:
* -fhonour-copts
If this option is not given, it's warned (depending
on environment variables). This is to catch errors
of misbuilt packages which override CFLAGS themselves.
* -Werror-maybe-reset
Has the effect of -Wno-error if GCC_NO_WERROR is
set and not '0', a no-operation otherwise. This is
to be able to use -Werror in "make" but prevent
GNU autoconf generated configure scripts from
freaking out.
* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
the default for -O2/-Os, because they trigger gcc bugs
and can delete code with security implications.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.
