scripts/gcc: Canadian Cross skip -print-multi-lib log output

Attempting to ${CT_TARGET}-gcc -print-multi-lib will fail

In do_cc_core_backend, for the final compiler in a canadian cross
baremetal, warn that multi-libs cannot be determined

In do_cc_backend, for either final compiler for a canadian cross,
warn that multi-libs cannot be determined

(Plus fixed CT_PREFIX_DIR in do_cc_backend to be ${prefix})

     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?
