It's often handy to make executables depend on each other, e.g. make a test depend on a helper. This doesn't work now, as linker will attempt to use the helper as an object. To fix, filter only relevant file types before linking an executable. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> --- rules.mak | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
