[Minios-devel] [UNIKRAFT PATCH] plat/xen/xenbus: Add _GNU_SOURCE define when using asprintf

[Bogdan Lascu <lascu.bogdan96@xxxxxxxxx>]

Compiling xenbus.c and xs.c gives the warning "implicit definition
of asprintf". Asprintf is not C nor POSIX, so its declaration is
conditioned by a header define that is activated by defining _GNU_SOURCE
before including stdio.h.
