7.105 '.weak NAMES'
===================
This directive sets the weak attribute on the comma separated list of
symbol 'names'. If the symbols do not already exist, they will be
created.
On COFF targets other than PE, weak symbols are a GNU extension.
This directive sets the weak attribute on the comma separated list of
symbol 'names'. If the symbols do not already exist, they will be
created.
On the PE target, weak symbols are supported natively as weak
aliases. When a weak symbol is created that is not an alias, GAS
creates an alternate symbol to hold the default value.
