(urgent) RFR: JDK-8200409: jdk11 nightly solaris sparc build failure

[Magnus Ihse Bursie]

If I understand the fix correctly, it will resolve the build issue. However, libjsig will not work, since we will not export any symbols at all. 

For this to work, we also need to filter out the fvisibility/xldscope flags from CFLAGS. 

I apologize for the mess I created. :-(
