I'm unable to compile the latest git master on an old i686 Linux (Fedora)
system I still use. See errors below.
The last time I compiled on this system was Mar 29, 2017 and it worked
fine. The commit ID was (247d0339ca5ddab692aee49baf43cd1324466028).
Here's truncated output from make. I'm happy to provide more details,
just not sure what would be useful. The git clone, and configure ran
without any errors. make showed no errors until the ones below.

make: *** [libavfilter/x86/af_afir.o] Error 1
Based on the error messages, it looks like it might not be getting the
correct values for HAVE_ALIGNED_STACK and ARCH_X86_64?
$ egrep 'HAVE_ALIGNED_STACK|ARCH_X86_64' config* ffbuild/*
config.asm:%define ARCH_X86_64 0
config.asm:%define HAVE_ALIGNED_STACK 1
config.h:#define ARCH_X86_64 0
config.h:#define HAVE_ALIGNED_STACK 1
ffbuild/config.mak:!ARCH_X86_64=yes
ffbuild/config.mak:HAVE_ALIGNED_STACK=yes
It appears the "ffbuild" subdir that contains all the config files was
added at some point between Mar 29th and now... Maybe that has something
to do with it?
FYI. If I do the following, everything works fine:
$ git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg-20170712-247d0339ca
$ cd ffmpeg-20170712-247d0339ca
$ git checkout 247d0339ca
$ configure
$ make
