util-linux: fix compilation when libc lacks wide-character support

Browse Source 
A recent change in util-linux left calls to wcstok and wcspbrk not
guarded by "#ifdef HAVE_WIDECHAR". This causes build failures when
libc does not have the wide-character functions, like some uClibc
builds.

Solve the problem by means of a patch already sent upstream.

Subject: [PATCH] column: fix compilation when libc lacks wide-character
support
Commit 4762ae9d removed mtsafe_strtok() but left behind calls to wcstok
and wcspbrk. This leads to build failures when libc does not have the
wide-character functions, like some uClibc builds.
Solve the problem by using strtok_r and strpbrk when HAVE_WIDECHAR is
not defined.
