Fix for sigaction Bug

[Andreas Jaeger]

Compiling statically I received:

/builds/glibc/20000621-static/libc.a(sigaction.o): In function `__libc_sigaction':
/usr/src/cvs/libc/signal/../sysdeps/unix/sysv/linux/i386/sigaction.c:69: multiple definition of `__sigaction'
/builds/glibc/20000621-static/linuxthreads/libpthread.a(signals.o):/usr/src/cvs/libc/linuxthreads/signals.c:136: first defined here
/opt/binutils/bin/ld: Warning: size of symbol `__sigaction' changed from 231 to 470 in sigaction.o
collect2: ld returned 1 exit status
make[2]: *** [/builds/glibc/20000621-static/nscd/nscd] Error 1
make[2]: Leaving directory `/usr/src/cvs/libc/nscd'

The appended patch fixes this problem.  Ok to commit?
