minimal: New port, intended to represent minimal working code. Unlike bare-arm, which is mostly intended to show raw interpreter size, without library and support code dependencies. This port is intended to be a better base to start new ports, and also will include emulation build to allow debug some aspects of embedded targets on POSIX systems. This initial commit is verbatim copy of bare-arm code.

minimal: Convert "bare-arm" port to "minimal" port. This enable libc functions, GC, and line-editing function. Also, UART emulation for POSIX systems is added. Emulation build is set as default.

Makefiles: Remove duplicate object files when linking. Scenario: module1 depends on some common file from lib/, so specifies it in its SRC_MOD, and the same situation with module2, then common file from lib/ eventually ends up listed twice in $(OBJ), which leads to link errors. Make is equipped to deal with such situation easily, quoting the manual: "The value of $^ omits duplicate prerequisites, while $+ retains them and preserves their order." So, just use $^ consistently in all link targets.
