RFR: 8351399: AIX: Better solution than JDK8348663

[Joachim Kern]

With
[JDK-8348663](https://bugs.openjdk.org/browse/JDK-8348663) [AIX] clang pollutes the burned-in library search paths of the generated executables
an ugly workaround was introduced to get rid of the unwanted list of search libraries the clang compiler automatically burns into the executable files.
Now we have a better solution, using just a different linker flag.
Instead of using the linker option -bnolibpath, which forces the LIBPATH env variable to be burned in, we now use the -blibpath:/usr/lib:lib option, which explicitly tells what to burn in.
I will revert the last change of [JDK-8348663](https://bugs.openjdk.org/browse/JDK-8348663) and introduce this new change.
