Fix geogram: fix legacy_numeric with gcc10.

-fcommon
  In C code, this option controls the placement of global variables defined without an initializer, known
  as tentative definitions in the C standard.  Tentative definitions are distinct from declarations of a
  variable with the "extern" keyword, which do not allocate storage.

  The default is -fno-common, which specifies that the compiler places uninitialized global variables in
  the BSS section of the object file.  This inhibits the merging of tentative definitions by the linker so
  you get a multiple-definition error if the same variable is accidentally defined in more than one
  compilation unit.

  The -fcommon places uninitialized global variables in a common block.  This allows the linker to resolve
  all tentative definitions of the same variable in different compilation units to the same object, or to a
  non-tentative definition.  This behavior is inconsistent with C++, and on many targets implies a speed
  and code size penalty on global variable references.  It is mainly useful to enable legacy code to link
  without errors.
