[PATCH] tools build: use .s extension for preprocessed assembler code

From: Masahiro Yamada
Date: Sun Jan 31 2016 - 13:00:44 EST


The "man gcc" says .i extension represents the file is C source code
that should not be preprocessed. Here, .s should be used.

For clarification,
.c ---(preprocess)---> .i
.S ---(preprocess)---> .s
