This includes the ABI (h), adds the endianess (l), and implies a
architecture level (v7). The name for the most common configurations
should be as short as possible so I'd rather drop the 'l' and add a
'b' or 'eb' if anyone wants a big endian distro in the future. The
architecture level is a problem as the loader should also be valid on
ARMv5 and ARMv6 hard float builds. Skype should be able to make a
hard float binary that runs on everything, including a potential ARMv6
hard float RaspberryPi build.

This introduces both a new directory and a new style for naming :)
