With "PCbuild\build.bat -d -e", OpenSSL fails building:

  nasm: fatal: unable to open input file `Z:\cpython\default\externals\openssl-
  1.0.1j\tmp32\aes-586.asm'

Detailed build log is:

It seems there are problems with how the file paths are computed? Also, I have no file "aes-586.asm", how is it supposed to be generated?
