RFR: JDK-8151302: Attempt at silencing build log broke html32.bdtd

[Erik Joelsson]

InJDK-8146403 <https://bugs.openjdk.java.net/browse/JDK-8146403>, I 
accidentally added a $(LOG_INFO) to the DTDBuilder command. The problem 
is that this command prints its generated output to stdout, which we 
pipe to a file. The LOG_INFO macro instead redirects this to /dev/null 
unless a high enough log level is active. Luckily, in JPRT and RE 
builds, we run with LOG=debug so the generation works, but for normal 
developer builds, it's currently broken.
