and export them to userland. - Define __HAVE_REG32 on platforms that define a reg32 structure and check for this in <sys/procfs.h> to control when to export prstatus32, etc. - Add prstatus32_t and prpsinfo32_t typedefs for the 32-bit structures. libbfd looks for these types, and having them fixes 'gcore' in gdb of a 32-bit process on a 64-bit platform. - Use the structure definitions from <sys/procfs.h> in gcore's elf32 core dump code instead of duplicating the definitions.
