Subject: [PATCH] fix build with gcc 10

Fix the following build failure with gcc 10 (which defaults to
-fno-common):

/home/buildroot/autobuild/instance-2/output-1/host/bin/x86_64-linux-gcc -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Os   -fno-schedule-insns2  -fno-schedule-insns -fno-inline-small-functions -fno-caller-saves -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DBUILD_MAIN -Wimplicit-function-declaration -Dx64_BIT  -o i7z i7z.o helper_functions.o i7z_Single_Socket.o i7z_Dual_Socket.o -lncurses -lpthread -lrt -lm
/home/buildroot/autobuild/instance-2/output-1/host/opt/ext-toolchain/bin/../lib/gcc/x86_64-buildroot-linux-gnu/10.2.0/../../../../x86_64-buildroot-linux-gnu/bin/ld: i7z_Dual_Socket.o:(.bss+0x0): multiple definition of `global_ts'; i7z_Single_Socket.o:(.bss+0x0): first defined here
