Synchronize OpenMP flags with AC_OPENMP

[Christian Feld]

Dear all,

the attached patch synchronizes the OpenMP flags detected in AC_OPENMP
with the flags that libtool 'func_append's to

  compiler_flags
  compile_command
  finalize_command
  new_inherited_linker_flags

and prepends to

  compile_deplibs
  finalize_deplibs

The patch includes -qopenmp (Intel) and -Kopenmp (Fujitsu) proposed to
AC_OPENMP, see [1][2], and uses just -homp for Cray, see [3].

It would be nice if this patch could make it upstream.

Thanks,
Christian
