[Bug 1371636]

[Emil-l-velikov]

Building OpenCL works like a charm here. Can you try to establish which
(if any) of the following components is responsible - llvm, gcc (*cough*
4.9.2_alpha) binutils or clang.

I'm building it on Archlinux (llvm 3.5.0, gcc 4.9.1 (snapshot
4.9-20140903), binutils 2.24 [1], clang 3.5.0).

[1] The binutils package has a patch which suspiciously looks like it should handle the issue

Title:
  [2.24.51.20140918-1ubuntu1 regression] - /usr/bin/ld: .eh_frame_hdr
  refers to overlapping FDEs

Status in The ARB phylogenetic analysis suite:
  New
Status in Mesa:
  Confirmed
Status in “binutils” package in Ubuntu:
  Confirmed

Bug description:
  Since today mesa fails to build on Ubuntu 14.10 (both i386 and amd64)
  while it still builds fine on Ubuntu 14.04. Nothing relevant changed
  in mesa since previous build in my PPA (indeed just some vc4 code only
  built on arm), the bug is reported by ld which I noticed just got
  updated with binutils package.
