Subject: [PATCH] Rebuild cross compilers when sources change

ONE_SOURCE=yes cross-compilers currently only depend on tcc.c, which
itself has no further deps.  So e.g. changing tccgen.c or tcctok.h
don't automatically rebuild cross compilers.  Let's go over
the intermediate $(X)tcc.o file which automatically depends on
LIBTCC_INC, which are all relevant source files.
