illumos gate

as discovered with the latest SS12. 5, there has been an intermediate SUNW_1.22.7 symbol version
added in Solaris that is trivial for illumos to support via the attached patch.

Simple testing done:

richard@omnis:/home/richard/src/tasprintf$ cat tasprintf.c 
#include <stdio.h>
#include <stdlib.h>

int
main(int argc, char *argv[])
{
    char *buffer;
    int len = 0;

    len = asprintf(&buffer, "Hello World");
    if (len < 0) {
        perror("asprintf");
        return (len);
    }

    printf("%s(len=%d)\n", buffer, len);
    free(buffer);

    return (0);
}
