2546	Cannot build bjam on Linux with vacpp	ccambly@…		"If we try to build bjam on linux using xlC the build fails because of an invalid linker option.  The file tools/jam/src/build.jam has the following:

## IBM VisualAge C++
toolset vacpp xlc : ""-o "" : -D
     :
     [ opt --release : -s -O3 -qstrict -qinline ]
     [ opt --debug : -g -qNOOPTimize -qnoinline -pg ]
     -I$(--python-include) -I$(--extra-include)
     : -L$(--python-lib[1]) -l$(--python-lib[2]) -bmaxdata:0x40000000 ;

The -bmaxdata linker option is only valid on AIX.  If I am building with xlC on Linux that linker option should not be specified.

The change in the patch file is:

## IBM VisualAge C++
{
local linkopt = ; if $(OS) = AIX { linkopt = -bmaxdata:0x40000000 ; }
toolset vacpp xlc : ""-o "" : -D
     :
     [ opt --release : -s -O3 -qstrict -qinline ]
     [ opt --debug : -g -qNOOPTimize -qnoinline -pg ]
     -I$(--python-include) -I$(--extra-include)
     : -L$(--python-lib[1]) -l$(--python-lib[2]) $(linkopt) ;
}
