This was accomplished by adding some pretty nasty hacks to the FFmpeg recipe
so that we can compile it for the GCC2 ABI using GCC7. This works because
GCC's C ABI has not changed between GCC2 and GCC7.
As a consequence of this, pretty much all the longstanding issues of the
ancient-and-still-miscompiled FFmpeg 0.10 are now completely gone.
Fixes #5080, #8461, #12696, #12436, #13981#13410, #13337.
Closes (possibly fixed earlier) #8605, #8511, #6984.
Probably fixes (couldn't test) #13989, #11974.
x86 is unaffected, as already mentioned. This breaks the build,
but since this diff was large, I wanted to have the functionality
changes be clear, so they are in the next commit.
The packages that remain are only the ones used somewhere in Jam
(including ones off by default, e.g. Wonderbrush, Live555.)
The x86 repo is untouched as it is being phased out and has no buildmaster-
generated equivalent.
