bug#3531: 23.0.94; Configure still sets mac-fix-env although its deleted

For the nextstep port configure(.in) still sets the target
"mac-fix-env". This breaks the command "make bootstrap" because the
Makefile in lib-src tries to build that target.

Here the occurences of "mac-fix-env":
---
$ find . -type f | xargs grep mac-fix-env
./configure:    LIB_SRC_EXTRA_INSTALLABLES=mac-fix-env
./configure.in:    LIB_SRC_EXTRA_INSTALLABLES=mac-fix-env
./doc/emacs/ChangeLog:  (Environment variables): Remove mention of mac-fix-env, which is
./lib-src/.cvsignore:mac-fix-env
./lib-src/ChangeLog:    * mac-fix-env.m:
./lib-src/ChangeLog:    * Makefile.in (mac-fix-env): Remove.
./lib-src/ChangeLog:    * Makefile.in (mac-fix-env): Compile it using ALL_CFLAGS.
./lib-src/ChangeLog:    * Makefile.in (mac-fix-env): Remove #ifdef around rule.
./lib-src/ChangeLog:    * .cvsignore: Add mac-fix-env.
./lib-src/ChangeLog:    * mac-fix-env.m: New file, automatically update
./lib-src/ChangeLog:    * Makefile.in: Add -universal to CFLAGS on OS X, add mac-fix-env to
./nextstep/README:                              and other bug fixes. mac-fix-env utility.
