Bug#1067483: postfix: please make the build reproducible

[Chris Lamb]

Source: postfix
Version: 3.9.0-1
Severity: wishlist
Tags: patch

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
postfix could not be built reproducibly:

 /usr/share/doc/postfix/examples/makedefs.out
  # AUXLIBS=-lssl -lcrypto -lsasl2 -lpthread
 -# AUXLIBS_CDB=-lcdb
 +# AUXLIBS_PCRE=-lpcre2-8
 +# AUXLIBS_PGSQL=-lpq
 +# AUXLIBS_MYSQL=-lmysqlclient
 +# AUXLIBS_SQLITE=-lsqlite3
  # AUXLIBS_MONGODB=-lmongoc-1.0 -lbson-1.0

This is caused by printing the output of "env" without piping it
through sort(1) — see the attached patch. We don't need to specify
LC_ALL=C as this is already done on line 189.
