* libc/sys/linux/Makefile.am: Add sig.c and sigaction.c. Also make siglist.inc dependent on sig.c instead of signal.c. * libc/sys/linux/Makefile.in: Regenerated. * libc/sys/linux/sig.c: Rename from signal.c and change code to use NSIG instead of _NSIG. * libc/sys/linux/sigaction.c: New file. * libc/sys/linux/signal.c: Changed to be linux signal() function so as to override regular newlib default signal.c. * libc/sys/linux/linuxthreads/config.h: Add __ASSUME_REALTIME_SIGNALS definition. * libc/sys/linux/linuxthreads/testrtsig.h: New file. * libc/sys/linux/machine/i386/Makefile.am: Remove sigset.c. * libc/sys/linux/machine/i386/Makefile.in: Regenerated. * libc/sys/linux/machine/i386/sigset.c: Moved to linux main directory. * libc/sys/linux/sigset.c: Moved from machine/i386 directory. * libc/sys/linux/sys/signal.h: Redefine NSIG to _NSIG and override default linux sigset_t typedef by defining it equal to __sigset_t. * libc/unix/sigset.c: Add check so code isn't compiled on systems with a sigset_t that isn't implemented with a single int.
