RFR: 8329131: Fold libjli_static back into libjli on AIX [v2]

[Magnus Ihse Bursie]

> On AIX, we need a static libjli, since the linker cannot find other libraries (like libjvm.so and libjava.so) using a relative path, as on other platforms.
> 
> However, for reasons unclear, we still build a dynamic libjli.so on AIX, even though this is never used. Instead, we also build a static libjli_static.a library (which is then forced to have a different name as to not collide with the dynamic library).
> 
> This should be fixed. We should build exactly one libjli on all platforms, be it static or dynamic.
