Add this option to vacpp when building bjam (-bmaxdata:0x40000000).
This option increases the amount of heap / stack space available
to bjam when it runs. By default on IBM SP2 clusters, the available
stack is limited to 256 Mb which is insufficient for building larger
applications.
-bmaxdata=<num>
Sets the maximum size of the area shared by the
static data (both initialized and uninitialized)
and the heap to <num> bytes. The default is
-bmaxdata=0.
