[8u] Request for approval for 8207057: No debug info for assembler files

[Severin Gehwolf]

Hi,

Please approve this backport request for JDK-8207057. Since the build
system is different in JDK 8 the JDK 12 patch has been ported to 8 and
reviewed on build-dev, by Erik Joelsson:

Bug: https://bugs.openjdk.java.net/browse/JDK-8207057
webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8207057/jdk8/01/
Review-thread: http://mail.openjdk.java.net/pipermail/build-dev/2018-September/023292.html

Since this change includes generated_configure.sh changes, please
advise whether I can push this myself (once approved) or need an Oracle
sponsor.

Thanks,
Severin
