libtcc.c: fix compilation failure (inconsistent tcc_add_file_internal)

gcc -o libtcc1.o -c lib/libtcc1.c -O2 -Wall
libtcc.c: At top level:
libtcc.c:1063: error: static declaration of 'tcc_add_file_internal' follows non-static declaration
tccelf.c:2915: note: previous implicit declaration of 'tcc_add_file_internal' was here
