[COMMITTED] ada: Update doc for -gnatw_q

[Marc Poulhiès]

From: Bob Duff <duff@adacore.com>

The -gnatw_q switch turns on warnings for noncomposing "="
operators. This patch updates the doc to refer to relevant
RM paragraphs.

gcc/ada/

	* doc/gnat_ugn/building_executable_programs_with_gnat.rst:
	Add RM references.
	* gnat_ugn.texi: Regenerate.

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