Bug#987700: bornagain: buggy cmake file

[Yangfl]

Source: bornagain
Tags: patch

Hi,

cmake/BornAgain/Linux.cmake currently has the following lines:
  execute_process(COMMAND uname -m OUTPUT_VARIABLE SYSCTL_OUTPUT)
  if(${SYSCTL_OUTPUT} MATCHES x86_64)
      message(STATUS "Found a 64bit system")
      set(BIT_ENVIRONMENT "-m64")
      set(BORNAGAIN_ARCHITECTURE linuxx8664)
  else()
      message(STATUS "Found a 32bit system")
      set(BIT_ENVIRONMENT "-m32")
      add_definitions(-DEIGEN_DONT_ALIGN_STATICALLY=1)
  endif()

This has the following affects:
  * It stops cross building since it reads build's `uname`.
  * It stops building for most non-amd64 64-bit archs since it doesn't
recognize them as 64-bit archs.
  * It stops building for most non-i386 archs since they don't accept `-m32`.

Please consider applying this patch.
