Subject: kconfig: ensure strndup() declaration is visible
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=0f4fd0de7532c08bdd77a46f101e5ca1220cd163;p=people%2Fdariof%2Fxen.git

kconfig: ensure strndup() declaration is visible

Its guard was updated such that it is visible by default when POSIX 2008
was adopted by glibc. It's not visible by default on older glibc.

Fixes: f80fe2b34f08 ("xen: Update Kconfig to Linux v5.4")
