Bjam is unable to build our applications on our IBM using xlC 7.1.
By default, the IBM limits available stack to 256 Mb. For some of
our applications, this is inadequate. I'd like to patch the tools/
jam/src/build.jam for vacpp to permit bjam to use a larger memory
segment by default. If we do this, it will help avoid failures
building Boost in the future as the number and size of Boost
libraries grows.

This is the behavior building one of our applications without the
patch applied.

Illegal instruction (core dumped)

I'd like to add -bmaxdata:0x40000000 to the debug and release build
options for vacpp in build.jam. A description of what this option
does from the xlC man page.

                 static data (both initialized and uninitialized)
                 and the heap to <num> bytes. The default is

Can someone review this patch and, if it's acceptable, commit it to
the head of the repository? If I don't hear from anyone if a few
days, I'll assume it's okay to commit it myself.
