[11u] RFR: 8243059: Build fails when --with-vendor-name contains a comma

[Severin Gehwolf]

Hi,

Could I please get a review of this 11u backport of a build fix? The
jdk/jdk patch does not apply cleanly since JDK-8222510[1] isn't in
OpenJDK 11u. I.e. this makes the context different and the patch
failing to apply. I've manually ported the patch. The gist is:

$(VERSION_CFLAGS) => $$(VERSION_CFLAGS)

Bug: https://bugs.openjdk.java.net/browse/JDK-8243059
webrev: http://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8243059/jdk11/01/webrev/
original change: https://hg.openjdk.java.net/jdk/jdk/rev/dff3aabdc2f3

Testing: Build fails before, passes after patch. java.vendor property
is as expected when it includes commas.

Thoughts?

Thanks,
Severin
