Support ldbl-opt libm_alias_double use from .S files [committed]

[Joseph Myers]

This patch makes the ldbl-opt libm_alias_double implementation support
use from .S sources, by adding a semicolon after its use of
weak_alias.

Tested (compilation only) with build-many-glibcs.py for
alpha-linux-gnu, in conjunction with a patch introducing uses of
libm_alias_double in alpha .S files.  Committed.
