Reverse out because the lack of using pgport in timezone/ is causing

problems:

Support cross compilation by compiling "zic" with a native compiler.
This relies on the output of zic being platform independent, but that is
currently the case.

-     <envar>CFLAGS</>, etc. should refer to the build tools for the
-     host architecture.  During the build process, the time-zone
-     database for PostgreSQL is created and a special tool to do that
-     is compiled and run during the build process.  This tool needs to
-     be compiled using a native compiler.  Specify this compiler using
-     the variable <envar>CC_FOR_BUILD</envar>.  Cross compilation
-     requires expert knowledge and the support for this process in the
