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" Update the README.md

## 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

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
