Due to the current linker command line ordering, parts of lib(min)c
that are used exclusively by libmagic end up not being instrumented,
which then causes problems transferring pointers such as _ctype_tab_
and _tolower_tab_. As a temporary workaround, we redefine the macros
that use those pointers. A better long-term solution should
eventually render this patch obsolete.
