Runtime support has been there a long time. Even sarge I think.

# ldconfig -v | grep /      
/usr/lib/i486-linux-gnu:
/usr/local/lib:
/lib/x86_64-linux-gnu:
/usr/lib/x86_64-linux-gnu:
/lib:
/lib32:
/usr/lib:
/usr/lib32:
/usr/lib/i486-linux-gnu/i686: (hwcap: 0x0008000000000000)
/usr/lib/tls: (hwcap: 0x8000000000000000)
/usr/lib32/i486: (hwcap: 0x0002000000000000)
/usr/lib32/i686: (hwcap: 0x0008000000000000)
/usr/lib32/i586: (hwcap: 0x0004000000000000)
/usr/lib/i486-linux-gnu/i686/cmov: (hwcap: 0x0008000000008000)
/usr/lib32/i686/cmov: (hwcap: 0x0008000000008000)

Even hwcaps function within multiarch dirs.
