Bugzilla Bug 234192

When trying to emerge xsb, portage stop complaining about unrecognized switches
in ./configure step: -with-mt -with-perl and -enable-prolog.


Reproducible: Always

Steps to Reproduce:
1. emerge dev-lang/xsb


Actual Results:  
./configure fails


./configure --help makes me understand that:
- with_mt switches should be -enable-mt (1 line to change in ebuild)
- enable-interprolog should be -with-interprolog (1 more line)

I don't know what to do with -with-perl...
Also occurs to me on an amd64 box
