Comment (by joel.sherrill):

 This is a patch which makes the VBE_RM enabled only when POSIX is. I see
 the pthread mutex usage in three files and am not sure of the usage. It
 may be possible to replace all of the mutex usage with an atomic bool
 which indicates it is in use.  The usage is really just to ensure only one
 open occurs at a time.

 This disables the driver which I don't think is what we want. There are
 three files which need addressing. And start.S calls a vesa method which
 still needs to be provided. So the fix needs to be thought out.
