The commit 605f38177d (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.
The fix for BZ#18231 requires new symbols only for sh4eb. This patch
adds the required folder and files for both BE and LE abilist. No
semantic changes are expected.
Checked with check-abi for sh4eb-linux-gnu and sh4-linux-gnu.
