 executed on SSE2 capable CPU, but under control of OS which does not
 support SSE2 extentions. Even though you can manipulate the value
 programmatically, you most likely will find it more appropriate to set
 up an environment variable with the same name prior starting target

 Alternatively you can reconfigure the toolkit with no-sse2 option and
 recompile.
