-												Introduce 'spec' subdirectories to outline aspects

Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:

  repos/base/include/spec
  repos/base/mk/spec
  repos/base/lib/mk/spec
  repos/base/src/core/spec
  ...

Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.

-												base-linux: add ARM support

This patch introduces a new platform 'linux_arm' for building and running
Genode/Linux on an ARM device.

Known limitations:

- libc 'setjmp()'/'longjmp()' doesn't currently save/restore floating
  point registers

Fixes #746.

-												linux: explicitly add well-known include paths

Unfortunately, the 'gcc -dumpmachine' magic does not suffice on all
Linux distros, so we just add the well-known paths for i386-linux-gnu
and x86_64-linux-gnu.

Fixes #1694

-												base-linux: 64-bit ARM support

This patch adds support for running Genode/Linux on the AARCH64
architecture.

- The kernel-agnostic startup code (crt0) had to be extended to
  capture the initial stack pointer, which the Linux kernel uses
  to pass the process environment. This is in line with the
  existing startup code for x86_32 and x86_64.

- The link order of the host libraries linked to lx_hybrid
  programs had to be adjusted such that libgcc appears at last
  because the other libraries depend on symbols provided by
  libgcc.

- When using AARCH64 Linux as host, one can execute run scripts
  via 'make run/<script> KERNEL=linux BOARD=linux' now.

-												Define _GNU_SOURCE for all users of syscall lib

Move the definition of '_GNU_SOURCE' from 'import-lx_hybrid.mk' to
'import-syscall.mk' because this definition may (potentially) affect all
programs that include Linux headers installed on the host - not only
hybrid Linux/Genode programs. Fixes #52
