[patch] elimnate MALLOC_INCOMPATIBLE

Hello,

The attached eliminates the xm*.h macro MALLOC_INCOMPATIBLE.  Only SunOS 
  4.x was defining it and more recent changes have made it unnecessary.

This in turn lets the xm file be deleted.

  @code{bfd_seek}).  FIXME, should be replaced by SEEK_SET instead,
  which is the POSIX equivalent.
  
- @item MALLOC_INCOMPATIBLE
- Define this if the system's prototype for @code{malloc} differs from the
- @sc{ansi} definition.
- 
  @item MMAP_BASE_ADDRESS
  When using HAVE_MMAP, the first mapping should go at this address.
