This fixes compilation of gdb on arm64.
The kernel defines "struct sigcontext" in asm/sigcontext.h and musl libc
defines it in signal.h, which collides.
Kernel 4.14 misses the definitions of struct user_sve_header so we still
have to use the aarch64-sve-linux-sigcontext.h header file which also
provides that and make sure aarch64-sve-linux-sigcontext.h does not
provide the same headers as the kernel or musl.

Support for following targets and native configurations has been removed:
m88k running OpenBSD (m88*-*-openbsd*)
SH-5/SH64 ELF (sh64-*-elf*)
SH-5/SH64 (sh*)
SH-5/SH64 running GNU/Linux (sh*-*-linux*)
SH-5/SH64 running OpenBSD (sh*-*-openbsd*)
Various Python API enhancements
Aarch64/Linux enhancements:
SVE support.
Hardware watchpoints improvements for entities stored at unaligned addresses.
New "c" response to disable the pager for the rest of the current command.
C expressions can now use _Alignof, and C++ expressions can now use alignof.
Improved flexibility for loading symbol files.
The 'info proc' command nows works on running processes on FreeBSD systems as well as core files created on FreeBSD systems.
A new --enable-codesign=CERT configure option to automatically codesign GDB after build (useful on MacOS X).

Seems others are running into this as well.
The problem seems to be that some code may be built
as C++ and not C, which may explain the linker error.
On this thread reply:
https://sourceware.org/ml/gdb/2016-11/msg00045.html
it mentions that the simulator should not call GDB's
"error" function directly, but rather use the "host_callback"
struct.
I have no idea about the use of the GDB simulator within
the OpenWrt/LEDE community.
So, I took the easier route, which is to disable the simulator.
(Also suggested here: https://sourceware.org/ml/gdb/2016-11/msg00047.html )
If needed, I can make an effort to fix the simulator for PPC.

ARC port of GDB is not yet upstream so we need to use
sources from Synopsys GitHub repo.
Given Synopys' commitment to upstream ARC support in GDB
in the nearest future it might be simpler to add a separate
package for ARC GDB instead of patching generic GDB package.
This way once ARC GDB stuff gets uptreamed we'll only need
to remove that new "gdb-arc" package.
Note 1 very minor change in generic gdb package was done -
it now depends on !arc (while "gdb-arc" depends on "arc").

Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.
I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.
However, I can not garantee that I always picked the correct information
and/or did not miss license information.
