[PATCH] Makefile: fix location of listing produced by "make subdir/foo.s"

[Jonathan Nieder <jrnieder@gmail.com>]

When I invoke "make block-sha1/sha1.s", 'make' runs $(CC) -S without
specifying where it should put its output and the output ends up in
./sha1.s.  Confusing.

Add an -o option to the .s rule to fix this.  We were already doing
that for most compiler invocations but had forgotten it for the
assembler listings.

Hi,

This patch is from below the scissors at
http://thread.gmane.org/gmane.comp.version-control.git/201434/focus=201485

I think it's a good change, but as usual it's nice if someone else
takes a look at it and gives it a sanity check.  If it seems sane,
I'd be happy to see it applied.  What do you think?

Thanks,
Jonathan
