RFR(XS): 8148353: [linux-sparc] Crash in libawt.so on Linux SPARC

Hi Dean,

> How does this relate to CCallingConventionRequiresIntsAsLongs?  Can you just set it to true for Sparc?  It seems like fixing a similar issue on ppc64 required a lot more changes, so I'm concerned we might be missing something.

That sounds like a good suggestion. Here is a new webrev:
