    test: fix bisecting issue in fuzzer-find-diff.pl
    
    Before bisecting to find the exact test which has failed, we
    first need to make sure that the first test is fine (the first
    test is "good" and the whole range is "bad"). Otherwise
    test 2 gets incorrectly flagged as problematic in the case
    if we already got a failure on test 1 right from the start.

    test: OpenMP 2.5 requires signed loop iteration variables
    
    Unsigned loop variables are only supported since version 3.0
    of OpenMP specification. Changing loop variables to use int32_t
    type fixes pixman build problems with path64 compiler.

    configure.ac: add iwmmxt2 configure flag
    
    The flag allows the user to select whether pixman-mmx.c is compiled with
    -march=iwmmxt or -march=iwmmxt2.
    
    gcc has scheduling support for the Marvell CPU in the XO 1.75 when
    building with -march=iwmmxt2.

    autotools: use custom build rule to build iwMMXt code
    
    gcc has no sane way of enabling iwmmxt code generation, like -msse for
    SSE, so you have to use -march=iwmmxt{,2}. User CFLAGS are placed after
    -march=iwmmxt and override the march value, so we have to use a custom
    build rule to order the CFLAGS such that pixman-mmx.c will be built with
    the necessary CFLAGS.
