title: Error using make on Windows with MinGW
body: <p>I'm fairly new to using "make" for anything, but I am forced to try and build some binaries with it for some C files (the code is not mine). It works for most of the files in the directory, but when it reaches the "usb" directory this happens:</p>
  
  <pre><code>make[1]: Entering directory 'C:/bios_memimage/usb'
  /bin/rm -fr scraper.bin
  process_begin: CreateProcess(NULL, /bin/rm -fr scraper.bin, ...) failed.
  make (e=2): The system cannot find the file specified.
  Makefile:10: recipe for target 'scraper.bin' failed
  make[1]: *** [scraper.bin] Error 2
  make[1]: Leaving directory 'C:/bios_memimage/usb'
  Makefile.mingw:14: recipe for target 'subdirusb' failed
  make: *** [subdirusb] Error 2
  </code></pre>
  
  <p>I'm unfamiliar with what "bin/rm -fr" means, and looking for it has not yielded much of anything. I can tell it's not creating the process, but what, exactly is it failing to find? And is there a remedy for it?</p>
