[Buildroot] [PATCH 0/4] Fix lttng-tools build issue

[Thomas Petazzoni]

Hello,

This set of patches fix the lttng-tools build issue with gcc 4.7.x and
gcc 4.8.x, by:

 * Adding appropriate patches to gcc 4.7 and gcc 4.8 in the internal
   toolchain backend.

 * Allowing external toolchains to indicate whether they are affected
   by the bug. For now, one toolchain known to be affected is marked
   as such, the other toolchains will have to be tested progressively.

 * Making the lttng-tools depend on toolchains not affected by the
   bug.

Thomas Petazzoni (4):
  gcc: add fix for PR 58595 to gcc 4.8.2
  gcc: add fix for PR 58595 to gcc 4.7.3
  toolchain: add option to declare toolchains affected by gcc PR 58595
  lttng-tools: mark as affected by gcc bug 58595
