Fixes: https://autobuild.buildroot.net/results/8d14173f31922a737c326be75aa24c9f9471342a/
The vde2 source code uses empty argument function pointer prototypes like:
typedef ssize_t (* ssize_fun)();
extern ssize_fun vdehist_vderead;
In C17 and earlier, such prototypes means unknown number of arguments,
whereas with C23 it means no arguments, leading to build failures:
libvdehist.c:39:27: error: initialization of 'ssize_fun' {aka 'long int
(*)(void)'} from incompatible pointer type 'ssize_t (*)(int, void *,
size_t)' {aka 'long int (*)(int, void *, long unsigned int)'}
[-Wincompatible-pointer-types]
Workaround it using -std=gnu99. Vde2 is provided both as a host and target
package, so do this unconditionally for both.
