Bug#949860: libretro-mupen64plus FTCBFS from amd64: unrecognized -msse flag

[Helmut Grohne]

Source: libretro-mupen64plus
Version: 2.0+git20160207+dfsg2-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

libretro-mupen64plus fails to cross build from source, because it uses a
uname based architecture detection and thus tries to use a -msse flag
when being built on amd64. Please always pass the relevant platform and
ARCH variables to make to avoid the detection entirely and thus making
the build more predictable. The attached patch implements that for your
convenience.
