[01/14] stdio-common: Remove _IO_vfwscanf
Checks
Commit Message
The symbol has never been exported, so no compatibility symbol is
needed. Removing this file prevents ld from creation an exported
symbol in case GLIBC_2_0 expands to a symbol version which
does not have a local: *; directive in the symbol version map file.

There is also a decl in libio/libio.h, and a reference to iovfwscanf in
sysdeps/ieee754/ldbl-128ibm-compat/Makefile.
