Subject: [PATCH 2/7] [PATCH] Remove duplicated variable definitions

When building on Fedora 32 (with GCC 10), following error is observed:

/usr/bin/ld: erase_info.o:/tmp/makedumpfile/makedumpfile.h:2010: multiple definition of
 `crash_reserved_mem_nr'; elf_info.o:/tmp/makedumpfile/makedumpfile.h:2010: first defined here
/usr/bin/ld: erase_info.o:/tmp/makedumpfile/makedumpfile.h:2009: multiple definition of
 `crash_reserved_mem'; elf_info.o:/tmp/makedumpfile/makedumpfile.h:2009: first defined here
/usr/bin/ld: erase_info.o:/tmp/makedumpfile/makedumpfile.h:1278: multiple definition of
 `parallel_info_t'; elf_info.o:/tmp/makedumpfile/makedumpfile.h:1278: first defined here
/usr/bin/ld: erase_info.o:/tmp/makedumpfile/makedumpfile.h:1265: multiple definition of
 `splitting_info_t'; elf_info.o:/tmp/makedumpfile/makedumpfile.h:1265: first defined here
...
collect2: error: ld returned 1 exit status
make: *** [Makefile:97: makedumpfile] Error 1

These variables are wrongly defined multiple times. So remove the
duplicated definitions.
