Samuel Martin a1a86ebfba liburcu: disable build with gcc-4.8.x on ARM 
Because of a gcc bug [1], liburcu checks for compiler version [2] and
stops the build prematurely if gcc-4.8.[0-2] is detected for ARM.

However a bug fix exists [3] and may be backported by ARM toolchain
providers; that's what is done in Buildroot [4] or Linaro [5].

So, this change:
- add a patch in liburcu to allow build with ARM gcc-4.8.2;
- adds a new hidden symbol to reflect the toolchain status with regard
  to this bug [1];
- and controls liburcu visibility.

However, a limitation of this is when the user is using a custom
toolchain; that's why the bug details have been added in the liburcu
help message.

Linaro toolchain for the ARM architecture. It uses Linaro

GDB 7.6), eglibc 2.18, Binutils 2013.10 (based on 2.23). It
generates code that runs on all Cortex-A profile devices,
but tuned for the Cortex-A9. The code generated is Thumb 2,
with the hard floating point calling convention, and uses
the VFPv3-D16 FPU instructions.
To use this toolchain, you must disable soft float usage.

The Linux kernel supports running both FDPIC and FLAT applications
concurrently if the binary format specific libraries are installed
properly. This option allows developer to install FDPIC libraries
into a buildroot rootfs image built with binary format that is not
FDPIC.
