[Buildroot] [PATCH] package/uclibc: fix ctype.h is*_l definitions

[Max Filippov <jcmvbkbc@gmail.com>]

ctype locale-specific macro definitions are broken because they result
in dereference of pointer to structure of incomplete type.
Drop these macros since they are optional and let applications use
functions with the same names.
