[COMMITTED] ada: GNAT UGN: Adjust wording in "Platform-specific Information" chapter

[Marc Poulhiès]

From: Joel Brobecker <brobecker@adacore.com>

The wording of the introduction paragraph specified an incomplete
list of OSes. Rather than trying to update the list, this commit
changes the text to make it more general. For those parts of
this chapter which only apply to specific OSes, the documentation
is written in a way that it is clear which OS it applies to.

gcc/ada/

	* doc/gnat_ugn/platform_specific_information.rst
	(_Platform_Specific_Information): Minor rewording of intro text.
	* gnat_ugn.texi: Regenerate.

Tested on x86_64-pc-linux-gnu, committed on master.
