It's a constraint imposed by gnulib that config.h needs to be the first
include file to be included in a compilation unit.

But more fundamentally, the use of gnulib is fundamentally broken regarding
clisp modules:
  - The clx module should not even see build/gllib/unistd.h.
  - The syscalls module should not rely on the getloadavg module from the
    clisp core. This is most evidently seen by a link error on AIX.
So, you cannot do anythere here until this fundamental mistake is fixed.
clisp's modules are designed as separately compilable units; therefore they
must use *independent* autoconf configurations; therefore their uses of
gnulib must be independent as well.
