devel/bloomberg-bde: tidy ports Makefile

- the build system uses -march=westmere, so restrict
  to that kind of architecture
- while here pet portlint

No bump to PORTREVISION because it still builds in the
same places and I dont' feel that a one-bit change to
COMMENT is worth re-packaging.

devel/bloomberg-bde: Clean up USES=python

Approved by:	portmgr (blanket)
With hat:	python

devel/bloomberg-bde: improve build a little

- fix build on 12.4
- add a testing target (builds *some* of the tests only)
- remove bundled pcre2 after stage (reported by diizzy@)
- teach portscout to ignore 'testtag'

devel/bloomberg-bde: new port for Bloomberg's foundational C++ libraries

BDE (Bloomberg Development Environment) is a collection of
libraries used inside Bloomberg. It's a bit like Boost, in
that it adds a whole spectrum of useful things to C++.
It's also like Boost in that things do flow from the library
into the language standard. BDE is Apache 2.0 licensed
and tracks modern C++ usage.

(This initial commit gets a library-that-builds into the
ports tree; it has no consumers yet so I won't swear that
it works completely)
