Jumping in the end of the thread here - sorry for that.

Another way to solve this would be to create two
small wrapper files:
aes-glue-neon.c - which include aes-glue.c
aes-glue-ce.c that include aes-glue.c

Then you could use standard kbuild support for building your module.
And we will not potentially break it when we change cc_o_c in the near future.
