This presentation has a useful summary of which optimisations and ABIs
various distros have chosen for their ARM support:

To save you all downloading 1.5Mb for <1K of text:
Ubuntu:
* “armel” (v7, Thumb 2, EABI soft-float)
still going, will ship in Precise (12.04), maybe with LTS?
* “armhf” (v7, Thumb 2, EABI hard-float)
mostly there, minor issues remaining
will ship in Precise unless major problem
Debian:
* “armel” (v4t, EABI soft-float)
still going, will ship in Wheezy (7.0)
* “armhf” (v7, Thumb 2, EABI hard-float)
mostly there, minor issues remaining
will ship in Wheezy unless major problems happen
OpenSUSE:
* “armv7hl” (v7, Thumb 2, EABI hard-float)
over 80% of the OpenSUSE archive built
aiming for inclusion in 12.2, freeze by beginning of June
aiming to be ready for SLED/SLES inclusion
* “armv5” (v5, EABI soft-float)
Secondary port, lower priority
Left for community effort
Fedora:
* “armv7hl” (v7, Thumb 2, EABI hard-float)
much of F15 built
aiming for inclusion as primary arch in F17, alpha build available
big push by F18, ready for RHEL 7
* “armv5tel” (v5, EABI soft-float)
much of F15 built
aiming for inclusion in F17, alpha build available
base for Fedora respin for Raspberry Pi
