Added mrbgems/mruby-bin-utils

[dearblue]

If this gem isn't accepted by the mruby project, I will release it in my personal repository.

Current problem:

• The switches that can be given to bin/mruby-cc depend on each compiler.
• When compiling only with bin/mruby-cc -c, I get a "'linker' input unused" warning; I checked with clang, but gcc does not.

😸 Perhaps some disgruntled person will rewrite it in C.

I think this line needs to be updated. You need to describe clearly what we get from these command-lines.

Some may misunderstand mruby-cc etc. only take one argument.

According to our current naming convention, we can expect the executable binary utils or mruby-utils from mruby-bin-utils.

In addition, maybe we can have mruby-build -c foo.c to compile single file, mruby-build -l *.o to link object files, and mruby-build foo.c foo.m to compile&link multiple files, etc. (mruby-build is just a name candidate).

Thank you for the review.

I can't think of anything else appropriate for the name. That said, it wouldn't be a good idea to separate them individually either.

As for mruby-build, I will explore the feasibility a bit more.
