Командная строка конфигурирования
./configure --sysroot=./ --target-os=none --arch=arm --cpu=am1808 --disable-mmx --disable-mmx2 --disable-asm --cc=armcc --enable-cross-compile

После некоторых разбирательств остановился на ошибке Error creating armcc configuration file.
Ввёл в файл конфигурации вывод текущёй информации

#elif $cc --vsn 2>/dev/null | grep -q "ARM C/C++ Compiler"; then
elif $cc --vsn; then
test -d "$sysroot" || die "No valid sysroot specified."

После запуски имею на экране

Error creating armcc configuration file.

If you think configure made a mistake, make sure you are using the latest
version from SVN. If the latest version fails, report the problem to the
ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.err" produced by configure as this will help
solving the problem.
