breakage via Templates/config.sub

[Christoph Moench-Tegeder]

Hi,

autoconf/automake-configure using ports fail to build on amd64 (not on
i386), as witnessed with the current pcre-8.33 port (and more, if you test
for it).
"make configure" (ultimatively, ./configure) bails out with

checking build system type... Invalid configuration `amd64-portbld-freebsd9.1': machine `amd64-portbld' not recognized
configure: error: /bin/sh ./config.sub amd64-portbld-freebsd9.1 failed
===>  Script "configure" failed unexpectedly.


Comparing an "original" config.sub (e.g. from pcre again) to the one
supplied in ports/Templates/config.sub, one cannot really miss the diff:

which quite obviously explains the trouble...

Bapt, you were the last committer on that file, could you please add the
evaporated lines back again?
