Subject: [PATCH] fix build with -j

Currently, if I try to build ruby from scratch with make -j, I get:

...
distcc gcc -g -O2   -I. -I.ext/include/i686-linux -I./include -I.  -DRUBY_EXPORT -D_GNU_SOURCE=1   -o strlcat.o -c ./missing/strlcat.c
distcc gcc -g -O2   -I. -I.ext/include/i686-linux -I./include -I.  -DRUBY_EXPORT -D_GNU_SOURCE=1   -o dmyext.o -c dmyext.c
./miniruby -I./lib  ./enc/make_encdb.rb ./enc encdb.h
make: ./miniruby: Command not found
make: *** [encdb.h] Error 127
make: *** Waiting for unfinished jobs....

The attached patch attempts to address the issue.

Paul
