As described at:
4520524ba0
this commit continues a series of updates of ARC tools.
This engineering build fixes the kernel dwarf stack unwinder feature for
ARC targets.
We still keep GDB as it is of arc-2016.03 release because there're some
issues we'd like to resolve before releasing it to wider audience.
So again note this is next engineering builds of arc-2016.09 series
and it might have all kinds of breakages, please don't use it for
production builds.

Some architectures, f.e. Blackfin doesn't support to configure GCC with
--with-cpu to set some CPU specific default CFLAGS (-mcpu=foo). Use a
hidden config symbol to give a hint which architecture supports it,
otherwise add defaults to toolchain wrapper for internal toolchains.

When we build the list of patches to include to compute the hash for
ccache, a typo precented the special gcc-initial/ and gcc-final/
directories from a global patch dir to be included in the calculation.
Fix that by properly expanding the $(PKG) variable.

BR2_TOOLCHAIN_BUILDROOT_WCHAR is only defined when uclibc is selected,
whereas BR2_USE_WCHAR is always defined. Due to this, we were disabling
quadmath support even with glibc or musl.
So, use BR2_USE_WCHAR to drive the gcc libquadmath option.
In addition, invert the logic of the condition to use positive logic,
and rework the comment to no longer mention gcc 4.6: libquadmath still
exists, and it still requires wchar support.

With this commit we're starting a series of updates of ARC tools.
Significantly rewritten arc-2016.03 tools introduced way too many
problems highlighted by Buildroot autobuilder. Now in attempt to
resolve as many issues as possible by the time final release of
arc-2016.09 tools is cut we'll be executing arc-2016.09 series
with engineering snapshots like this one.
We decided to go this way instead of applying separate patches here
and there because ongoing development introduces quite a lot of
changes and separate patches are not practical in Buildroot.
Moreover this will give us very clean visibility of number of
issues we see (hopefully it will decrease over time).
One of the important changes introduced in this engineering build
is initial set of changes for proper support of PIE on ARC in terms
of both building on host and running on ARC target. I expect some
PIE-related build breakages to go away and new ones will be treated
as the high-priority issues to be fixed ASAP.
For now we only update Binutils and GCC while keeping GDB
as it is of arc-2016.03 release because there're some issues
we'd like to resolve before releasing it to wider audience.
So again note this is one of the first engineering builds of
arc-2016.09 series and it might have all kinds of breakages,
please don't use it for production builds.

In commit f4682cf933, a hash of the patches applied to gcc was created
to make sure that ccache can properly detect when the toolchain has
changed. The patches applied to gcc consist of the buildroot patches in
package/gcc, but also potentially patches in BR2_GLOBAL_PATCH_DIR.
However, the path to the patches in BR2_GLOBAL_PATCH_DIR was corrected
incorrectly, because it misses a /. So instead of:
$(BR2_GLOBAL_PATCH_DIR)/gcc-initial/*.patch
it would look for
$(BR2_GLOBAL_PATCH_DIR)gcc-initial/*.patch
In other words, if BR2_GLOBAL_PATCH_DIR doesn't end with /, the patches
in BR2_GLOBAL_PATCH_DIR are not taken into account in the ccache hash.
To fix, add the missing /

This commit updates the gcc musl patches for gcc 4.7, 4.8 and 4.9 so
that the path to the dynamic linker encoded as "program interpreter"
in the generated binaries actually matches the symbolic link installed
by musl when building for mips soft-float.
Indeed, musl installs a symlink called ld-musl-mipsel-sf.so.1, but gcc
currently generates binaries that use /lib/ld-musl-mips.so as program
interpreter.
The fix is simply the one from
https://bitbucket.org/GregorR/musl-cross/commits/825219202365, i.e
adjust MUSL_DYNAMIC_LINKER in our musl gcc patches.
Thanks to these patches:
$ ./host/usr/bin/mipsel-linux-readelf -a ./target/bin/busybox
[...]
[Requesting program interpreter: /lib/ld-musl-mipsel-sf.so.1]
[...]
gcc 5.x doesn't need any fix because the musl patches already use the
right value.

Building with -mtune=e6500 led to build failures in glibc (probably in
uclibc as well) because gcc was built for a 32-bit target even though
the target tuple is powerpc64-*. This lead to a mix of 32-bit and
64-bit support and build errors like:
fatal error: gnu/lib-names-32.h: No such file or directory
The root cause is that the configure script is not handling e6500
correctly, because of stupid typo in the condition.
