8323667: Library debug files contain non-reproducible full gcc include paths

[andrew-m-leonard]

Native library debug files contain the full gcc system include paths, which then results in the native library being non-reproducible (via the CRC bytes), if built with differing gcc include path location.
This is a backport of the jdk fix to -fdebug-prefix-map these gcc paths when absolute paths are not allowed for a release build.
