Subject: flex: propagate m4 dependency on wchar
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c0d30d4c94047ab29db021a921dc3762e81ac5e7;p=buildroot.git

flex: propagate m4 dependency on wchar

Commit fe6a9e5e9d4046173a60235f8fd9a3b4746929c6 missed the fact that
m4 has a dependency on wide char support, so this dependency should be
propagated to flex.

Fixes:
