12.04 may be deprecated, but it's still supported by Ubuntu until April 
2017.  There are plenty of IT departments that would be hesitant to roll 
out full OS upgrades once every two years.

Regardless, I don't build libcxx with the system GCC, I build with 
Clang.  So long as libcxx can target libc from the 12.04 (and maybe even 
10.04!) era, then I won't be personally affected.
