-----------------------------------------+----------------------------------
 When building boost libraries with xlc on a PPC64 Linux platform (though
 building in 32-bit mode -- it's a RHEL5 system), I have two issues.
 (Actually, I had three, but the third one has already been reported and
 fixed):

  * Boost is passing -qpic, but we find that we really need -qpic=large in
 order to avoid problems loading
  * Shared libraries are not built with the -soname option being passed to
 the linker, which causes several problems, though I believe these are all
 well understood.

 I suspect the vacpp configuration has been tested most thoroughly on AIX,
 which is the reason for these omissions.

 I have attached a patch that addresses both issues.  The patch applies
 cleanly to 1.37.

 **NOTE** This patch is Linux-specific.  It would be easy to make these
 properly conditional on Linux so they don't get applied on non-Linux
 platforms, but since I have only linux to test with and am not that
 familiar with bjam, if I were to attempt this, it would just be a guess
 anyway.  I'm sure someone who is familiar with bjam can very easily apply
 this fix correctly rather than just accepting my incomplete patch as is.

 All the patch does is replace -qpic with -qpic=large wherever -qpic is
 passed to xlc, and add -Wl,-soname -Wl,<libname-without-dir> to
 vacpp.link.dll.
