branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
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.
