Erico Nunes 88db88d1b3 binutils: enable as target package for aarch64
binutils got disabled as a target package for aarch64 back in Buildroot
2012.11 (commit 660d16f4).
The default version 2.21.1 at the time didn't really support aarch64, as
shown by the autobuilder error reference in that commit.

binutils has now had support for aarch64 since 2.23, but was never
re-enabled for aarch64.

All of the binutils versions currently supported by Buildroot (oldest
being 2.24) support aarch64, so we can now enable it without any
restrictions.

This same patch also touches the dropwatch, lightning and oprofile
packages which all select binutils and had the 'depends on !aarch64' to
keep Kconfig consistent. They are now re-enabled for aarch64 as well.
They are changed in this same patch so that Kconfig is kept consistent
and doesn't end up having them disabled in a commit which only has the
binutils change applied.
lightning has other explicit arch dependencies so it is not actually yet
available in aarch64, but at least the dependency on !aarch64 because of
binutils is not needed anymore.

Everything has been build tested with Buildroot and external toolchains.
binutils and dropwatch work fine in a qemu target. oprofile doesn't seem
to be supported in the qemu aarch64 processor but builds fine and seems
to have some level of aarch64 support in the source, so there doesn't
seem to be a reason to keep it disabled in Kconfig.

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
