[XXS] 8199858 : solaris-x86_64 : unpack200 fails linking with SS12u4

[Baesken, Matthias]

Hello , could you please review this small fix for Solaris x86_64 ?

We were running into  build errors  for  unpack200   on Solaris x86_64  because of missing symbol  "environ"  .
The patch adds  environ  to the mapfile  .

( seems this is a similar / same   problem  already  solved for Solaris Sparc   with

https://bugs.openjdk.java.net/browse/JDK-8172548

JDK-8172548<https://bugs.openjdk.java.net/browse/JDK-8172548>  :  unpack200 fails linking with new update of SS12u4    )
