[Skiboot] [PATCH] Makefiles: Remove --Wno-stringop-truncation

[Oliver O'Halloran]

To disable a warning you use the command line parameter:

	 -Wno-<warning-name>, not
	--Wno-<warning-name>

GCC seems to ignore parameters starting with a double dash, so we've
been building with the stringop-trunction warning enabled for about a
year now and no one has complained. Away it goes.

Fixes: cd2b103f2488 ("Makefile: Check -Wno-stringop-truncation is supported")
