On BeOS, compilation fails like this:
source='ls.c' object='ls.o' libtool=no \
DEPDIR=.deps depmode=gcc /bin/sh ../build-aux/depcomp \
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I. -I../lib -I../lib -Wall

/boot/home/gnubuild/coreutils-6.0/src/ls.c: In function `main':
/boot/home/gnubuild/coreutils-6.0/src/ls.c:1199: `SA_RESTART' undeclared (first
use in this function)
/boot/home/gnubuild/coreutils-6.0/src/ls.c:1199: (Each undeclared identifier is
reported only once
/boot/home/gnubuild/coreutils-6.0/src/ls.c:1199: for each function it appears
in.)
BeOS has a sigaction function with SA_NOCLDSTOP, but no SA_RESTART. This
workaround does it.

BeOS portability.
* src/ls.c (SA_RESTART): Fallback define.
