Summary of the bug:
While trying to build 32bit version of static ffmpeg on 64bit debian
(3.2.0-2-amd64), the following error occurred:
{{{
/root/ffmpeg-static/src/ffmpeg/libavcodec/bitstream.c:348:1: error: unable
to find a register to spill in class ‘AREG’
}}}
I was using the following config:
(Since the trac reported an error "Warning: Ticket description is too long
(must be less than 262144 characters)", here is a pastebin:

Shortly:

This is what it looked like near the end of the make:
