libc6-sparcv9b 2.12-0ubuntu5 (sparc binary) in ubuntu maverick

 Contains the standard libraries that are used by nearly all programs on
 the system. This package includes shared versions of the standard C
 library and the standard math library, as well as many others.
 .
 This set of libraries is optimized for the UltraSPARC v9b ABI. It only
 needs to be installed on UltraSPARC machines. If you install this on a
 non-UltraSPARC, it won't even be used.
