Forcing things isn't going to work.  You must have the readline-dev 
package installed to have readline support, and the current code must 
have readline support to build.

You have found one bug in the build system - if readline is required, 
the configure step should stop and print an error message when it is 
missing.  Jeff has said he is going to fix that.

To make EMC2 compile, install readline-dev.

Making halcmd build correctly without readline support is possible but 
complex and IMO not worth the trouble.  As Jeff has pointed out, many 
Unix/Linux programs use readline, and its not unreasonable for EMC to 
depend on it.
