ASM_OUTPUT_WEAK_ALIAS documentation

[Aaron W. LaFramboise]

The ASM_OUTPUT_WEAK_ALIAS documentation in mainline
(http://gcc.gnu.org/onlinedocs/gccint/Label-Output.html#Label%20Output) is:

ASM_OUTPUT_WEAK_ALIAS (stream, name, value)  Macro
A C statement to output to the stdio stream stream assembler code which
defines (equates) the weak symbol name to have the value value. If value
is NULL, it defines name as an undefined weak symbol.
Define this macro if the target only supports weak aliases; define
ASM_OUTPUT_DEF instead if possible.

I don't understand what ASM_OUTPUT_DEF has to do with anything.  Does it
mean ASM_WEAKEN_DECL instead?
