PATCH: build zsh-5.8 on AIX 7.1

["Peter A. Castro" <doctor@fruitbat.org>]

Greetings, All,

  Found I needed to build zsh on AIX 7.1 and found a few things needing
simple tweaks to make it compile/link.  I'm a little surprised some of
this hasn't bubbled up on other platforms, but AIX has always been a
little schizophrenic, so whatever.

  Also found you needed to set CC and CFLAGS thus:
  CC=xlc
  CFLAGS="-qlanglvl=stdc99"

Don't know where that knowledge should be placed, but most other compile
options (ie: cc, c98, etc) produce weird errors.  The above probably
needs to go into configure somewhere.

  Sorry about the diff output here.  AIX's diff is pretty limited.
