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"

 * `static` generate static libraries.
-* `shared` generate shared libraries (Only for the Vhex kernel).
+* `dynamic` generate dynamic libraries (Only for the Vhex kernel).

 #### Building
 Create a build directory and configure in it:

 ```
 
 Then build the source and install the library files to the selected directory.
