Subject: [PATCH 3.16.y-ckt 056/168] arm64/crypto: fix makefile rule for aes-glue-%.o

3.16.7-ckt3 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andreas Schwab <schwab@...e.de>

commit 7c2105fbe9658d6cee18751568e29579bb58bfec upstream.

This fixes the following build failure when building with CONFIG_MODVERSIONS
enabled:

  CC [M]  arch/arm64/crypto/aes-glue-ce.o
ld: cannot find arch/arm64/crypto/aes-glue-ce.o: No such file or directory
make[1]: *** [arch/arm64/crypto/aes-ce-blk.o] Error 1
make: *** [arch/arm64/crypto] Error 2

The $(obj)/aes-glue-%.o rule only creates $(obj)/.tmp_aes-glue-ce.o, it
should use if_changed_rule instead of if_changed_dep.
