Hi,

I discovered that if bjam is presented with more than one occurrence  
of the timeout parameter (-l) on the command line, bjam will always  
use the first occurrence.  Often during regression testing, more than  
one -l option occurs on the command line.  This patch changes the  
logic to use the largest specified timeout value on the command line,  
rather than an order specific selection (i.e. always first, always  
last, etc...).

Tested on Darwin and Linux, okay to commit?
