The File I/O is at the top of the file. The #!/bin/sh means: this line
is a comment, but it's the first line, the ! means execute the following
program as an interpreter: "/bin/sh". If you don't have a /bin/sh,
you will get a "file not found" when your shell (your login shell bash)
tries to execute /bin/sh.

The "correct" thing to do is for the top-level configure to NOT do
"/path/to/config.sub" and hope it works. It should do
"$SHELL /path/to/config.sub". If $PATH is not set, it will evaluate
to nothing, and the first line of the file will be parsed. On
Win32, our makefiles should call "SHELL=bash.exe /path/to/configure",
so that SHELL will be set when it needs to be.
