Nimble and two different C files with the same name

[radekm]

Hi,

I'm trying to wrap libdeflate in Nim. I would like to create a package which 
doesn't depend on any external library so I embedded C sources of libdeflate 
inside my Nimble package.

Now I use following `compile` directives in my source code:
    
    
    {.compile: "libdeflate_gzip/private/libdeflate/lib/deflate_decompress.c",
      compile: "libdeflate_gzip/private/libdeflate/lib/utils.c",
      compile: "libdeflate_gzip/private/libdeflate/lib/arm/cpu_features.c",
      compile: "libdeflate_gzip/private/libdeflate/lib/x86/cpu_features.c",
      compile: "libdeflate_gzip/private/libdeflate/lib/crc32.c",
      compile: "libdeflate_gzip/private/libdeflate/lib/gzip_decompress.c"
    .}
    
    
    Run

Unfortunately when linking my test I'm getting error
    
    
    duplicate symbol '_libdeflate_init_x86_cpu_features' in:
        /Users/radekm/.cache/nim/test1_d/cpu_features.c.o
    
    
    Run

The problem is that there are two files `cpu_features.c` with the same name but 
in different directories. Then my linker is called with
    
    
    /Users/radekm/.cache/nim/test1_d/cpu_features.c.o
    
    
    Run

twice and I have duplicate symbols. I also suspect that `cpu_features.c` for 
x86 ovewrites one for ARM. Can you advice how can I solve this without 
modifying or renaming the original sources of libdeflate?
