[LLVMdev] configure with new target

[Vadim Khoptynets]

Tom, Krzysztof, Ahmed, thank you!

Updating the configure.ac script in projects/sample/autoconf and running
./autoconf/AutoRegen.sh have fixed my trouble. In error, I updated autoconf/
configure.ac instead projects/sample/autoconf/configure.ac. What difference
between these scripts?
