[8u] 8191006: hsdis disassembler plugin does not compile with binutils 2.29+

[David Buck]

Hi!

Please approve the backport to 8u-dev of this small fix to allow hsdis 
to build with modern versions of binutils.

bug report:
https://bugs.openjdk.java.net/browse/JDK-8191006

JDK 12 changeset:
http://hg.openjdk.java.net/jdk/jdk/rev/5064f30ac015

JDK 12 review thread:
http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2018-July/029928.html

JDK 12 changeset applies as-is to the 8u-dev source after file path 
unshuffling.

Cheers,
-Buck
