That's almost certainly a bad idea. You never want to copy/paste
stuff that can be shared among different BSPs. Instead, let
your Makefile just pull in the sources from another BSP.
Ideally, such shared pieces (involves most of the things under
libbsp/powerpc/shared/vme) should eventually go into a separate library
to be used by different BSPs.

I got to compile everything in < 15min. All I had to do was
modify the pc386 BSP's Makefile.am and add a BSP specific
VMEConfig.h:

1) Modify Makefile.am:

Index: Makefile.am

  libbsp_a_LIBADD = ../../../libcpu/@RTEMS_CPU@/cache.rel \

2) Add new VMEConfig.h  ***NOTE*** the actual values I defined there
   are ***BOGUS*** -- they are specific to a particular board and you
   should revise them. I have no pc386 hardware with VME available.
   ( I attached a template that I put into libbsp/i386/pc386/include )

3) run ampolish3 to update 'preinstall.am'

     ampolish3 Makefile.am > preintall.am

4) (unless you configured your rtems with --enable-maintainer-mode)
   re-run 'bootstrap', configure RTEMS and build.
