--- Comment #2 from Fangrui Song <i at maskray.me> ---
FORCE_COMMON_ALLOCATION (force_common_definition in binutils-gdb/ld/ldlang.c)
is only useful for -r.

-r linking with a linker script is rare... Since there is an alternative (-dc),
I think we can claim this to be a wontfix.

I think FORTRAN 77 COMMON block is strongly discouraged. Note, GCC head (the
future 11 release) defaults to -fno-common. Clang is following suit
