Comment(by slyfox):

 A note:

 what is missing in fedora/debian patch is:
 - the real request for libffi's library and include path via pkg-config.
 - ./configure time convigurability

 Gentoo, for example, allws multiple libffi headers in the following
 locations:
 /usr/lib64/libffi-3.0.11/include/ffi.h
 /usr/lib64/libffi-3.0.11/include/ffitarget.h
