This patch fixes various things which make the build more reproducible. Some changes
here only change intermediate artefacts but that means when you have two build trees
giving differing results, the differences can be isolated more easily. The issues here
usually become apparent with longer paths.
This was all debugged with:
TMPDIR = "${TOPDIR}/tmp"
vs.
TMPDIR = "${TOPDIR}/tmp-inital-mylongpath-mylongpath-mylongpath-mylongpath-mylongpath-mylongpath-mylongpath-mylongpath-mylongpath"
The patch specifically:
* Sorts output in GNUmakefile
* Always generates indirect flags files used to avoid pathlength issues else the
compile commands suddenly change when using longer paths
* Sorts the AutoGenTimeStamp file contents
* Makes the TargetDescBlock objects from BuildEngine sortable to allow the makefile fix
* Fix ElfConvert within GenFw so that only the basename of the binary being converted
is used, else the output from "GenFw XXX.bin" differs from "GenFw /long/path/XXX.bin"
with sufficiently long paths
Upstream-Status: Pending [At least some of this might be interesting to upstream]
