[Spice-devel] [PATCH spice-gtk] build-sys: require recent pkg-config

[marcandre.lureau at redhat.com]

From: Marc-André Lureau <marcandre.lureau at redhat.com>

So we can drop the AC_SUBST for _CFLAGS & _LIBS variable (since 0.24
but there is no clean way to check that before PKG_PREREQ in 0.29,
released last year)
