libffi: bump to version 3.3-rc0

- Update site to github (for the time being, as 3.3-rc0 is a release
  candidate, it is not published on the official ftp)
- Update third patch
- Remove fourth and fifth patches (already in version)
- Remove uneeded hooks, as public headers are now installed in the
  standard path since

-Subject: [PATCH] mips: use __linux__ and not linux
-
-The "linux" symbol is not POSIX compliant [1], and therefore not
-defined when building with -std=c99. Due to this, the linux
-conditional block doesn't get used on Linux when building Python 3.x
-(which is built with -std=c99). To fix this, we use the POSIX
-compliant __linux__ symbol, which is defined when -std=c99 is used.
-
-This fixes the build of Python 3.x on MIPS/musl configuration, as it
-makes sures that <asm/sgidefs.h> gets included and not <sgidefs.h>.
