libstdc++, Darwin: Fix weak attribute to use __weak__ instead of weak.
The text for _GLIBCXX_WEAK_DEFINITION has used 'weak' for the attribute name,
since its intoduction. Amend to use the implementation namespace '__weak__'
version.
Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>
libstdc++-v3/ChangeLog:
* config/os/bsd/darwin/os_defines.h (_GLIBCXX_WEAK_DEFINITION): Use the
implementation namespace for the weak attribute.
