[sharutils] Does not compile with -fno-common

Trying to build sharutils 4.15.2 with  -fno-common fails with

    [   30s]
    /usr/lib64/gcc/x86_64-suse-linux/9/../../../../x86_64-suse-linux/bin/ld:
    shar-opts.o:(.data.rel.ro.local+0x0): multiple definition of
    `program_name'; shar.o:(.rodata+0x10): first defined here
    [   30s]
    /usr/lib64/gcc/x86_64-suse-linux/9/../../../../x86_64-suse-linux/bin/ld:
    ../lib/libgnu.a(md5.o): in function `md5_stream':
    [   30s] md5.c:(.text+0x15d): multiple definition of `md5_stream';
    shar.o:shar.c:(.text+0x28): first defined here


As -fno-common is going to be the default, I think this should be fixed.


Kind regards,
