 Make libffi install into a predictable directory (#9620)

 On some systems (depending on gcc multilib configuration) libffi
 would install into libffi/build/inst/lib64 even though we configure
 it with --libdir=libffi/build/inst/lib. There appears to be no way
 to get libffi to install to a predictable directory "out of the box",
 so we apply a small patch to Makefile.in. This is the same fix used
 in Gentoo's ebuild (https://bugs.gentoo.org/show_bug.cgi?id=462814).
