[Ada] Shorter display for shared library building

[Arnaud Charlet]

When a shared library is built, in non verbose mode, the displays
of the command used are now truncated if they are deemed too long.

Tested on x86_64-pc-linux-gnu, committed on trunk

2010-06-22  Vincent Celier  <celier@adacore.com>

	* mlib-prj.adb (Display): In non verbose mode, truncate after fourth
	argument.
	* mlib-utl.adb (Gcc): In non verbose mode, truncate the display of the
	gcc command if it is too long.
