Update configure script

* add early "-h" and "--help" handling
* replace "--support-<ABI_NAME>" flags by "--support=<target>,<target>,..."
* rename libraries name:
	* "libfxlibc-casio-abi-fx9860g" -> "libfxlibc-fx9860g"
	* "libfxlibc-casio-abi-fxcg5" -> "libfxlibc-fxcg50"

## Dependencies
Fx C library depends on a suitable GCC toolchain in the PATH. You can absolutely

#### Configuration and support
The Fx C library supports these ABI:
* `casio-abi-fx9860g` for the support of Casio ABI used by fx9860g-like devices.
* `casio-abi-fxcg50` for the support of Casio ABI used by the fxcg50 device.
* `vhex-kernel` for the support of Vhex kernel ABI.
* `fx9860g` for the support of Casio ABI used by fx9860g-like devices.
* `fxcg50` for the support of Casio ABI used by the fxcg50 device.
* `vhex` for the support of Vhex kernel ABI.
* (nothing) compile only standing functions.
The Fx C library support these format:
* `static` generate static libraries.
* `shared` generate shared libraries (Only for the Vhex kernel).
* `dynamic` generate dynamic libraries (Only for the Vhex kernel).
Note that the shared feature is not currently implemented because of
non-support of the shared library generation by the GCC compiler for SuperH

the dynamic symbols resolving (Thanks Kristaba).
For more information about library build configuration, you can use the
`../configure --help` command.
`./configure --help` command.
#### Building
Create a build directory and configure in it:
```
% mkdir build && cd build
% ../configure
% ../configure --static --support=vhex,fx9860g,fxcg50
```
Then build the source and install the library files to the selected directory.

* You must add `fxlibc/` instead of each include file (for example, if you want
to include `stdio.h` you mush use `#include <fxlibc/stdio.h>`.
* Link with:
* `-lfxlibc` for standalone feature
* `-lfxlibc-casio-abi-fx9860g` for Casio ABI support for monochrome devices
* `-lfxlibc-casio-abi-fxcg50` for Casio ABI support for primz devices
