Following gdb 7.12.1 removal [1] the host gcc version needs to be updated
since gdb >= 8.x now requires a C++11 compiler (gcc >= 4.8).
While at it, move BR2_HOST_GCC_AT_LEAST_4_8 under BR2_PACKAGE_HOST_GDB since
it's not an architecture dependency. Add a comment when the host gcc is too
old to build host gdb.

gdb 8.1 has a new optional dependency on mpfr, which according to the
NEWS file:
GDB now uses the GNU MPFR library, if available, to emulate target
floating-point arithmetic during expression evaluation when the
target uses different floating-point formats than the host. At
least version 3.1 of GNU MPFR is required.
So for the target gdb, this is unnecessary, and therefore we
forcefully disable mpfr support by passing --without-mpfr.
For the host gdb, it would potentially be useful, but since it's a new
feature that isn't essential, we for now keep it disabled as well. An
option may be added later if needed.
To avoid gnulib issues with uClibc/musl, we need to pass additional
configure/make variables, like is done in OpenEmbedded [1].
[1] http://git.openembedded.org/openembedded-core/tree/meta/recipes-devtools/gdb/gdb_8.1.bb?id=02664a8dcd1ebb6cd77248e1b97a78390ea06033#n9
We re-add the same patches as the ones present for gdb 8.0.1, except
0004-nat-linux-ptrace.c-add-missing-gdb_byte-cast.patch, which was
merged upstream.

As we are about to switch to 8.0 as the default gdb version, we
need to adjust how the gdb dependencies are handled. Indeed, from 8.0
onwards, gdb needs a C++11 capable compiler, i.e at least gcc 4.8.
Until now, Config.in.host was making sure that gdb 8.0 was not
selectable if the cross-compilation toolchain did not have C++ support
with gcc >= 4.8. This worked fine because the default version of gdb,
used as the target gdb version when no host gdb is built, was 7.11,
and did not require C++11.
With the switch to 8.0 as the default version, when target gdb is
enabled but not host gdb, 8.0 is used, which means we need a C++11
capable compiler. The dependencies in Config.in.host are no longer
sufficient.
So instead, we remove the target-related dependencies from
Config.in.host and move them properly to Config.in. The overall logic
is the following:
- In Config.in.host, BR2_PACKAGE_HOST_GDB_ARCH_SUPPORTS ensures that
we have at least host gcc 4.8 if we're on ARC, because the ARC gdb
needs C++11. We remove the target toolchain related dependencies
from here.
- In Config.in.host, the version selection ensures that 8.0 cannot be
selected if the host toolchain does not have at least gcc 4.8. We
remove the target toolchain related dependencies from here.
- In Config.in.host, we introduce a BR2_PACKAGE_GDB_NEEDS_CXX11
option, that indicates whether the currently selected version of
gdb requires C++11 support in the toolchain to build the target
variant. Even though this option is more related to the target
variant of gdb, we keep it in Config.in.host so that it appears
next to the definition of BR2_GDB_VERSION, to make sure they are
kept in sync.
