        * libc/sys/linux/Makefile.am: Add support for new files.
        * libc/sys/linux/Makefile.in: Regenerated.
        * libc/sys/linux/ids.c: Add __getuid weak alias for getuid.
        * libc/sys/linux/signal.c: Change to use real-time syscalls for
        sigsuspend, sigprocmask, and sigpending.  Also remove sigaction as
        it is in a separate file now.
        * libc/sys/linux/machine/i386/Makefile.am
        * libc/sys/linux/machine/i386/Makefile.in
        * libc/sys/linux/sys/signal.h: Add include of <bits/signum.h>.
        * libc/sys/linux/sigaction.c: New file.
        * libc/sys/linux/sigqueue.c: Ditto.
        * libc/sys/linux/sigwait.c: Ditto.
        * libc/sys/linux/machine/i386/sigaction.c: Ditto.
        * libc/sys/linux/kernel_sigaction.h: Ditto.
