This is a follow-up to

   https://sourceware.org/pipermail/cygwin/2020-July/245623.html

As I explained there, a patch applied to the Cygwin build causes php to often 
call mmap with MAP_FIXED, and some of these calls fail.  Removing the relevant 
hunk of the patch fixes the reported problem, and I don't see any reason why 
that hunk should be needed.

Obviously Yaakov had a reason for applying that hunk, and I'm guessing (hoping) 
that the reason is no longer applicable.

Ideally, someone should ITA php and deal with this.  That person will not be me. 
  I don't use php and I know nothing about it.  If no one steps forward, I would 
be willing to do a one-time non-maintainer upload.

I'm attaching the revised patch and a revised cygport file.  (It's Yaakov's 
cygport file, modified to account for the patch change, with a BUILD_REQUIRES 
added.)
