        Update support for x86 Solaris 2.
        * config/i386/tm-i386sol2.h, nm-i386sol2.h:  New configuration
        files for x86 Solaris 2.
        * config/i386/i386sol2.mt, i386sol2.mh:  Use them.
        * config/sparc/tm-sun4sol2.h (PROCFS_GET_CARRY):  New macro, extract
        carry flag from a given regset.
        (IS_STATIC_TRANSFORM_NAME):  New macro, check if a symbol name
        is a SunPro transformed name.
        * i386-tdep.c (sunpro_static_transform_name):  New function to
        extract the source name from a SunPro transformed name.
        * inferior.h (procfs_first_available, procfs_get_pid_fd):
        Add prototypes.
        * infrun.c (wait_for_inferior):  Handle breakpoint hit in
        signal handler without intervening stop in sigtramp.
        * procfs.c (procfs_lwp_creation_handler):  Use PROCFS_GET_CARRY
        instead of direct access to the status register.
        (procfs_get_pid_fd):  New function, returns procfs fd for a given pid.
        * sol-thread.c (ps_lgetLDT):  New function, returns LDT for a given
        lwpid.
        (sol_find_new_threads):  Handle failed libthread_db initialization
        gracefully.
        * stabsread.c (define_symbol):  Use IS_STATIC_TRANSFORM_NAME
        to check for a SunPro transformed symbol name.
