    sh: Add sh4 fpu Implies folder
    
    The commit 605f38177db (sh: Split BE/LE abilist) did not take in
    consideration the SH4 fpu support.
    
    Checked with a build for sh4-linux-gnu and manually checked that
    the implementations at sysdeps/sh/sh4/fpu/ are selected.
    
    John Paul Adrian Glaubitz also confirmed it fixes the build issues
    he encontered.
