- Allow LTO but only FAT LTO OBJECTS (boo#1133245)

- Add patch libsigsegv-2.12-lto.dif
  * Avoid redefinition of structures of <bits/sigcontext.h> by
    <asm/sigcontext.h>
  * Avoid moved logic in resulting assembler code for LTO objects
    in signal handler for segmentation faults

- Avoid none debugging libsigsegv, that is add -fno-lto (boo#1133245)
- Use %license if known

- Disable LTO (boo#1133245).
