Separate project configuration and build system

[powerbroker]

there are configuration subfolders in the /transistortester/software/trunk, e.g. 'mega328_MK-328', 'mega644_LCD2004' and so on, containing 'Makefile', specific for each configuration.
there are lots of configuration settings in the config-specific 'Makefile's, and a short build procedure definition. the most of settings are in form of compiler flags, defining macros.

it's extremely hard to enforce proper code assistance and to build project from sources within IDE(with it's own build procedure).

would be great to have configuration setting inside some header file, like default "avr/io.h" is done. depending on project's 'MCU Type' it includes corresponding IO definition header, e.g. 'avr/iom328p.h' in case of 'ATmega328P' or 'ATmega328'.
this way, 'to build the project user just include e.g. 'config.h', which in case of 'st7565_kit' includes default 'st7565_kit.h', in case of 'GM328' - default 'gm328.h', in case of custom schematics - 'custom.h'
