This patch fixes a warning
../include/features.h:328:4: warning: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Wcpp]
seen when building for ARM. This warning comes from libc-do-syscall.S
being built for nscd: the nscd build uses _FORTIFY_SOURCE, while .S
files aren't built with -O, and the combination produces a warning.
As _FORTIFY_SOURCE doesn't do anything for .S files, undefining it in
libc-do-syscall.S seems the simplest solution.
Tested for ARM.
