RFR: JDK-8148120 Incremental update from build-infra project

[Erik Joelsson]

In NativeCompilation.gmk, the exit value saving for linking is most 
likely redundant. I managed to remove that for the compile command 
lines. There I verified that failed compiles still failed the build, 
without the need for exitvalue saving. I do believe this was relying on 
the -e switch to bash (I tried both with and without that and pipefail 
to be sure which was required), but we do have that always on windows.
