The changes to the AC_RUN_IFELSE test programs do not have an effect
on Android since we are cross-compiling:

    checking whether dup2 works... guessing no
    checking whether fcntl handles F_DUPFD correctly... guessing no

In the current head of tree, lib/getdtablesize.c still calls sysconf()
on Android platforms, causing test-{dup2,getdtablesize,fcntl} to fail
on current released Lollipop/KitKat images.
