From what I can see the Creative Zen Vision ports, which were the only ones to set USE_ELF prior to the Echo R1 port, do not work except for a bootloader and never even got to the point of booting Rockbox. This explains why they build codecs and plugins as ELF binaries, yet there is no code to load ELF format codecs or plugins. Anyhow, add a new setting, PLUGIN_USE_ELF, which controls whether plugins & codecs are left as ELF or converted to flat binaries. This makes it possible for the Echo R1 to use the flat binary .rock format, and makes it possible to have ELF plugins/codecs on targets with non-ELF main binaries. Seeing as nothing needs ELF plugins/codecs right now, the new default is to generate them as flat binaries unless the target requests otherwise. Change-Id: I9ffae669978de5cc7ad214cd50d97ad6e8938394
