doc: Remove claim about ISO C
The patch to make -fcommon the default introduces a bogus claim into
the GCC documentation.
-fcommon was claimed to be incompatible with ISO C for preventing
duplicate definitions from being diagnosed. It does, but as that
elicits undefined behaviour (the requirement that there shall be no
more than one external definition is not a constraint), ISO C does not
require any diagnostic for it. In the absence of any other rule this
would violate, both -fcommon and -fno-common are fully compatible with
all versions of ISO C.
