They do, yes, but the problem is the C compiler doesn't understand GNU
make vpath directives, so the includes in lib/ are:

  -I$(srcdir) -I.

while the includes in cross/src/lib are:

  -I$(top_srcdir)/lib -I$(srcdir) -I.

and as a result, when a file in -I$(top_srcdir)/lib then includes:

  #include "stdio.h"

it gets the stdio.h in lib, and not cross/lib, leading to silent
problems later on.

Thanks.
