RFR [11u] : 8221318: [11u] do not disable c99 on Solaris

Fri Mar 22 08:50:29 UTC 2019

Hello, please review this change.

It is a downport of   jdk13 change    https://bugs.openjdk.java.net/browse/JDK-8215710     to  11u .

JDK-8215710  removed the disabling of C99 on Solaris in jdk13.
Reason was :
"Currently we disable C99 in the Solaris build by setting -xc99=%none%.
This differs from a lot of other build environments like gcc/Linux or VS2013/2017 on Windows where C99 features work.
We should remove this difference on Solaris and remove or replace the setting. "

It would be helpful to have this downported to jdk11, because it would make downporting changes easier (brings build settings of the releases closer together) .
(I was already  running  into   one issue   because  of the  different build settings )
