RFR: 8284661: Reproducible assembly builds without relative linking [v4]

[Andrew Leonard]

> This PR removes the need for relative object file linking introduced by JDK-8284437 for linux libraries, by specifying
> .file <relative source path> directives in the linux .S source files. The source files specify a .file ASSEMBLY_SRC_FILE
> where ASSEMBLY_SRC_FILE is defined by the NativeCompliation.gmk.
