[ublas] using intervals.

Hello,

Today I've compiled the bench5 using bjam which has been finished with
an error. This was caused because BOOST_UBLAS_USE_INTERVAL was defined
in bench5 bjam file (I didn't defined it in qmake build system). I've
fixed the compilation error by applying the attached patch.

Could BOOST_UBLAS_USE_INTERVAL be defined?

The message of the error was:
