Newer gcc v10 complains about globals being defined twice due to
a new default -fno-common flag. This causes build failures:
LINK t/fio-dedupe
/usr/bin/ld: t/arch.o:(.bss+0x4): multiple definition of `tsc_reliable'; gettime.o:(.bss+0x4): first defined here
collect2: error: ld returned 1 exit status
make: *** [Makefile:499: t/fio-dedupe] Error 1
Each of the tests which call arch_init() to initialize tsc_reliable:
File Function Line
1 t/dedupe.c main 536 arch_init(argv);
2 t/lfsr-test.c main 37 arch_init(argv);
3 t/stest.c main 86 arch_init(argv);
already link with gettime.o which defines tsc_reliable,
so there is no need to provide it from t/arch.c
