ARM hardfp port related documentation.

Notes on rpm bootstrap here. Notes on obs import here.

RPM architecture/subarchs

armv7hl = -mfloat-abi=hard -mfpu=vfpv3-d16 -march=armv7-a -mno-thumb

armv7nhl = -mfloat-abi=hard -mfpu=neon -march=armv7-a -mno-thumb

MeeGo.com baseline would be armv7hl, vendors can recompile for armv7hln if they so wanted

Currently, there're also plans to use thumb2:

armv7thl = -mfloat-abi=hard -mfpu=vfpv3-d16 -march=armv7-a -mthumb

armv7tnhl = -mfloat-abi=hard -mfpu=neon -march=armv7-a -mthumb
