Summary:                    Ninja generator causes build failure for ASM files
via NASM
Description: 
On Windows (haven't tested on other platforms), the Ninja generator for ASM
files compiled with NASM adds the "/showIncludes" flag to the NASM command line
in "rules.ninja":

    #############################################
    # Rule for compiling ASM_NASM files.

    rule ASM_NASM_COMPILER
      deps = msvc
      command = C:\dev\bin\nasm.exe  $FLAGS /showIncludes -f win64 -o $out $in
      description = Building ASM_NASM object $out

This causes a build failure with the error message:

"nasm: error: more than one input file specified"

Using YASM instead of NASM turns this into a warning instead of an error, but
inconvenient nonetheless.

Removing "/showIncludes" from the above line in "rules.ninja" fixes the error.

Steps to Reproduce: 
# Have nasm.exe in path #
git clone https://boringssl.googlesource.com/boringssl
mkdir build
cd build
cmake -GNinja ..
ninja
