  Log:
  Autoconf changes to support new ffi.
  
  These have only been tested on Linux so far - help testing on other
  platforms would be appreciated.  To test, search
  hugs98/src/unix/configure.in for HUGS_TRY_DYNLINK and add lines to
  test for the flags your platform needs.
  
  Changes:
  
  Added some GHC autoconfery for figuring out alignments, sizes, etc.
  (The results make it into header files but are currently ignored by
   all ffi code.)
  
  Added HUGS_TRY_DYNLINK to aclocal.m4
  This tries to build a loadable library, tries loading it, and
  figures out whether to use a leading underscore.  The loading test
  is a simplified version of the code in machdep.c.  Typical uses:
  
     HUGS_TRY_DYNLINK("/LD")
     HUGS_TRY_DYNLINK("-shared")
     HUGS_TRY_DYNLINK("-shared -nostdlib")
     HUGS_TRY_DYNLINK("-bundle")
     HUGS_TRY_DYNLINK("-bundle -lc")
  
  Killed the old test for leading underscores - it is subsumed by the
  new autoconf code (which performs a more direct test).
  
  Merged the different pieces of compile and link code in ffi.c into a
  single piece of code (by moving all configuration into autoconf).
