Subject: [PATCH 4.9 66/78] alpha: merge build rules of division routines

From: Masahiro Yamada <yamada.masahiro@...ionext.com>

commit e19a4e3f1bffe45b8e2ea67fcfb0c9c88278c4cc upstream.

These four objects are generated by the same build rule, with
different compile options.  The build rules can be merged.
