This patch set the names of the init and final procedures of
Stand-Alone Libraries to "ada_init" and "ada_final" if the name of the
library is "ada", to avoid duplicate symbols "adainit" and "adafinal" in
executables.
The test for this is to build an executable using a shared SAL with the
name "ada". It should behave as if the name of the SAL was different from
"ada".

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

2011-08-01  Vincent Celier  <celier@adacore.com>

	* mlib-prj.adb (Build_Library): Use "ada_" as the prefix for the "init"
	and "final" procedures when the name of the library is "ada", to avoid
	duplicate symbols "adainit" and "adafinal" in executables.
