Before this commit:
$ rake

$ rm build/host/src/gc.o
$ rake
rake aborted!
Don't know how to build task '/home/foo/mruby/build/host/src/gc.o' (See the list of available tasks with `rake --tasks`)
...
After this commit:
$ rake
...
$ rm build/host/src/gc.o
$ rake
CC src/gc.c -> build/host/src/gc.o
...
With gcc 9.3.0 on Ubuntu 20.04, build/host/src/array.d looks like:
/build/host/src/array.o: /src/array.c \
/include/mruby.h /include/mrbconf.h \
/include/mruby/common.h \
...
/include/mruby/range.h \
/src/value_array.h
and it has been parsed to:
[
# /src/array.c missing
"/include/mruby.h /include/mrbconf.h", # incorrectly parsed
"/include/mruby/common.h",
...
"/src/value_array.h",
]
After this change, *.d will be parsed correctly.
[
"/src/array.c",
"/include/mruby.h",
"/include/mrbconf.h",
"/include/mruby/common.h",
...
"/src/value_array.h",
]
Adding MRB_MINGW32_LEGACY in common.h in order to identify the legacy MinGW environment (i.e. NOT to be confused with MinGW-w64).

* `_Static_assert` can also be used with `-std=gnu99` on GCC >= 4.6.
* `static_assert` can be used on MSVC.
* `static_assert` can be used even on old G++/Clang++ if
`__GXX_EXPERIMENTAL_CXX0X__` is defined.
- Use POSIX format instead of GNU extension for `time` command.
For example FreeBSD's `time(1)` does not have GNU extensions available.
- Sort `benchmark/bm_*.rb`.
This is because the order of the bar graph cannot be uniquely
determined depending on the result of `Dir.glob`.
The function corresponding to `ht_hash_func()` was as follows in the days of
khash implementation (before d78acc7a).
```c
mrb_hash_ht_hash_func(mrb_state *mrb, mrb_value key)
{
enum mrb_vtype t = mrb_type(key);
...
switch (t) {
...
default:
hv = mrb_funcall(mrb, key, "hash", 0);
h = (khint_t)t ^ (khint_t)mrb_fixnum(hv);
break;
}
...
}
```
When switched to the segmented list implementation (d78acc7a), this function
was changed as follows.
```c
sg_hash_func(mrb_state *mrb, seglist *t, mrb_value key)
{
enum mrb_vtype tt = mrb_type(key);
...
switch (tt) {
...
default:
hv = mrb_funcall(mrb, key, "hash", 0);
h = (size_t)t ^ (size_t)mrb_fixnum(hv);
break;
}
...
}
```
Since the argument `t` was added, the variable for type tag was changed from
`t` to `tt`, but the variable used in the expression of `h` remained `t`.
Probably this is an omission of change, so fixed it.
