Added build support for stock MinGW/MSYS build of POCO.

Components now supported by default:
 Foundation {including internal PCRE lib}
 Util
 Net
 XML
 SQL
 SQL/ODBC
 SQL/SQLite
 samples/{all components supported}

Components supported with additional 3rd party MinGW/MSYS libs:
 NetSSL w/OpenSSH

Components unsupported at this time:
 testsuite: Fails to build due to TupleTest - needs slight code change MinGW can't deal with currently.  Only thing causing failure.
 CppUnit: Unable to support this due to WIN32 version of this functionality relying on MFC which does not ship with MinGW/MSYS.
 --no-wstring support due libstdc++ - will require STLPort {support coming soon}


:build/config/MinGW
 +Fixed compiler environment flags and switches
 +Linkage build supports:  SHARED, STATIC, or BOTH
 +Fixed duplicate symbol/unresolved symbol during compile
 +Added PCRE build flag for internal library build/eliminate link errors
 +Disable support of UTF-8 by default, MinGW will require STLPort 
 +Corrected system link libs for MinGW "dumb" linker

:build/rules/global
 +Added MinGW environment deduction logic

:configure
 +Fine tuned environment deduction recognizing MinGW as valid

:Data/ODBC/Makefile
 +Fixed correct ODBC libs to link

:Foundation/Makefile
 +Added logic for building correct subsystem dependency

:Util/Makefile
 +Added logic for building correct subsystem dependency
