-march forces the compiler to generate generic code, whereas -mcpu
allows it to target the specific CPU variant and use instructions that
the generic architecture may not have

Use kernel config as input instead of -march CFLAGS.
With this change, -march can be dropped and replaced with more specific
optimization flags for better code generation.

Currently system log is always included as a part of ubox.
Add logd as a seperate package and add it to default packages list.

Add $ARCH and $CPU_SUBTYPE to the package architecture strings to differentiate
low and big endian targets as well as extended instructions sets like NEON
or DSP2.
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
Use the more specific CPU_TYPE designation as default package architecture
and only fall back to ARCH if no specific CPU_TYPE is set.
This means that e.g. ar71xx packages will use "74kc" as architecture,
not "mips" which is a precondition for sharing packages between targets.

This patch introduces support of new boards with ARC HS38 cores.
ARC HS38 is a new generation of ARC cores which utilize ARCv2 ISA.
As with ARC770 we're addind support for 2 boards for now:
[1] Synopsys SDP board (AXS103)
This is the same base-board as in AXS101 but with
FPGA-based CPU-tile where ARCHs38 core is implemented.
[2] nSIM
Again this is the same simulation engine but configured for
new instruction set and features of new CPU.

Most of currently mentioned CFLAGS in arc770/Makefile
are not really required because:
[1] "-Os -pipe" are set by default in include/target.mk
[2] "-fno-caller-saves" gets enabled via menuconfig
as an extra compiler flag for developers
So the only one that makes sense is "-matomic" and
that one is really essential. Without it many software
packges won't build complainin on unresolved atomic ops.

This includes binutils, gcc, gdb and uClibc-ng.
Latest release of ARC gcc (as of today it is "arc-2015.06")
is based on upstream gcc 4.8.4.
Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/gcc
Latest release of ARC binutils (as of today it is "arc-2015.06")
is based on upstream binutils 2.23.
Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06
Latest release of ARC GDB (as of today this is "arc-2015.06-gdb")
is based on upstream gdb 7.9.1.
Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06-gdb
Note that for binutils and gdb that come from unified git repository
(which is the case for upstream binutils/gdb today) we need to disable
building of gdb in binutils and binutils in gdb hence in binutils:
------>8------
--disable-sim
--disable-gdb
------>8------
and in gdb:
------>8------
--disable-binutils
--disable-ld
--disable-gas
------>8------
Also in gdb we disable sim because if the following breakage while
building with it:
------------>8------------
/usr/bin/env bash ./../common/genmloop.sh -shell /usr/bin/env bash \
-mono -fast -pbb -switch sem5-switch.c \
-cpu a5f -infile ./mloop5.in \

With this patch the mips74k subtarget will be compiled with optimized
compiler options to generated smaller and faster code. This currently
breaks broadcom-wl, because the binary blob is only compiled with

Config symbols can have regular dashes, e.g.

So no substitution should be performed on the last part of the symbol.
