Apply asm redirections in syslog.h before first use [BZ #27087]
Similar to d0fa09a770, but for syslog.h when _FORTIFY_SOURCE > 0. Fixes [BZ #27087] by applying long double-related asm redirections before using functions in bits/syslog.h. Tested with build-many-glibcs.py. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
