[Findutils-patches] Avoid link failure with gcc -fno-common.

[Jim Meyering]

Without the following patch, gcc -fno-common fails like this:

./libfindtools.a(finddata.o):(.bss+0xb0): multiple definition of `starting_desc'
find.o:(.bss+0x0): first defined here
./libfindtools.a(finddata.o):(.bss+0xb8): multiple definition of `program_name'
find.o:(.bss+0x8): first defined here


        Avoid link failure with gcc -fno-common.
        * find.c (program_name, starting_desc): Declare "extern".
