- update some svn ignores

- don't fail to configure if threads aren't found, since
  we don't have thread support on windows
- rather than setting the asm file name to none in asm-data,
  special case windows w/ CL in the ompi_config_asm macros.
  Otherwise, there were some warnings during make dist and
  configure that didn't need to be there.

This commit was SVN r8502.
