Subject: [PATCH] fix build with gcc 10

Move initialisation of global variables to main functions to fix the
following build failure with gcc 10:

/tmp/instance-1/output-1/host/lib/gcc/arm-buildroot-linux-gnueabihf/10.2.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld: ./libgdbmapp.a(parseopt.o):(.bss+0x2c): multiple definition of `parseopt_program_args'; gdbm_dump.o:(.data.rel.local+0x28): first defined here
/tmp/instance-1/output-1/host/lib/gcc/arm-buildroot-linux-gnueabihf/10.2.0/../../../../arm-buildroot-linux-gnueabihf/bin/ld: ./libgdbmapp.a(parseopt.o):(.bss+0x30): multiple definition of `parseopt_program_doc'; gdbm_dump.o:(.data.rel.local+0x2c): first defined here
