The incentive for combining 32- and 64-bit binaries is mighty slim; in 
most cases where 32-bit is satisfactory, the 32-bit code runs as well or 
better on the 64-bit OS, while the larger size binary detracts from any 
advantage.
gcc has survived without providing much support for multiple paths, e.g. 
  non-SSE, SSE3, ... where the incentive might have been greater.
