complibs/cloog: add support for the ISL backend

CLooG 0.18+ will use ISL instead of PPL, so we have to configure
adequately depending of which backend is in use.

The Kconfig entries will decide for us which is selected, so we
can rely on either PPL xor ISL to be selected, not both.

Reported-by: "Plotnikov Dmitry" <leitz@ispras.ru>
[Dmitry did a preliminray patch to add ISL support,
which this patch is inspired from]

     4 Attached is a patch to add __attribute__ ((noinline)) to
     5 call_gmon_start.
     6 
     7 Without this patch, the sec script that processed initfini.s removes a
     8 part of inlined call_gmon_start, causing undefined label errors.
     9 
    10 This patch solves the problem by forcing gcc not to inline
    11 call_gmon_start with __attribute__ ((noinline)).
    12 
    13 Tested by building for arm-none-lixux-gnueabi.  OK to apply?
