[patch] assume working unix98 PTYs

[David Vrabel]

Hi,

It doesn't seem necessary to do configure time check for working UNIX98 
PTYs.  I would consider it sufficient to check for grantpt().

I considered making it a run time test but decided not to -- any 
reasonably recent system will have support for UNIX98 PTYs.
