commit a4217408a3d6050a7f42ac23adb6ac7218dca85f

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.
