Primarily to make the patch as unintrusive as possible: the code used

	#pragma weak foo

before, and it's probably very safe to assume that every platform that
supports this also supports #pragma weak foo = bar.  #pragma weak is used
in several places in GCC, and the deprecation doesn't really hold anymore,
with the introduction of #pragma GCC.
