[Bug-ocrad] configure doesn't handle spaces in paths

[Xavid Pretzer]

Hello,

I was recently installing ocrad and had to modify the configure script 
because both the directory I was compiling in and the destination 
directory had spaces in their path names.  ocrad doesn't seem to be on 
the alpha site linked to from the ocrad page, so I don't know if this 
has been fixed since the last released version, but I've attached a 
patch from version .15 that works for me.
