 It is easy to include and exclude modules but it must be done by editing makefile. Makefile specifies how the binaries are build when you execute _mingw32-make_.

 Determines what CPU instructions are allowed. USE_186 limits instructions to those supported by 80188/80186 and NEC V20/V30. USE_286 limits instructions for 286 compatible code and USE_386 limits instructions for 386 compatible code. XTIDE Universal BIOS uses macros that emulate the missing instructions when necessary. Do not use any of the mentioned preprocessor directives if you want to generate 8088/8086 compatible code.

 Assembles code targeted for AT systems. For example AT builds always operate in full operating mode. Another difference is that AT builds use some BIOS functions that are not available on XT systems.
