[0] We're making a "one time" incompatible ABI switch

the "hard float" ABI defined in section 6 of the ARM AAPCS (commonly
referred to as the ARM EABI - but that doesn't actually exist as a
name). The procedure call standard will be ARM AAPCS vfpv3-d16, as
defined in section 6 of that document. Other distros are switching and
this will form the basis of any LSB standardization effort later on.
Think of v7 and v5 as being different arches, which they are really.
And to further clarify:
- This is an addition, not a switch -- the intention is to continue to
support armv5tel in addition to armv7hl at this time -- Tegra and
Marvell Kirkwood (including plug computer) devices which do not support
armv7hl will continue to work with armv5tel.
- The significant incompatibility is hardfp vs. softfp ABI (moreso than
v7 vs. v5).
