More make updates - Githubissues

Hex and bin outputs have explicit rules.
Removed print_info rule, merged into link rule.
Simplified build output to a single line per operation, such as Compiling foo/bar.c. Full output can be enabled with VERBOSE=1.
Colorized output. Enabled by default for ttys, can be disabled with USE_COLOR=0.
Set the target exe extension by compiler, using .axf for armcc.
Only include linker script dependencies if it is being preprocessed. This fixed make_armcc.
More well defined C preprocessing flags.
Use order-only prerequisite to create the build output directory.
Cleaned up rm command in clean rule.
Added a simple help rule.
