[patch] invert -Wno-attributes logic to talk about -Wattributes

[Mike Frysinger <vapier at gentoo dot org>]

the current documentation lists out a whole bunch of -W flags and then says 
for -Wall "enables everything mentioned above" ... this is incorrect as above 
it talks about -Wno-attributes rather than -Wattributes

attached patch inverts the documentation to discuss -Wattributes rather 
than -Wno-attributes so as to be consistent with the rest of the document and 
so the -Wall statement is correct
