lex implicit rule chain is broken

[Mohamed Akram]

echo "lang: lang.l" > Makefile

echo "%%" > lang.l

make

Output:

lex  -t lang.l > lang.c

cc    -c -o lang.o lang.c

cc   lang.o lang.l   -o lang

/usr/bin/ld: lang.l: file not recognized: file truncated

collect2: error: ld returned 1 exit status

make: *** [<builtin>: lang] Error 1

rm lang.o lang.c

It tries to link the .l file.
