1This patch fixes various things which make the build more reproducible. Some changes
2here only change intermediate artefacts but that means when you have two build trees
3giving differing results, the differences can be isolated more easily. The issues here
4usually become apparent with longer paths.
5
6This was all debugged with:
7TMPDIR = "${TOPDIR}/tmp"
8vs.
9TMPDIR = "${TOPDIR}/tmp-inital-mylongpath-mylongpath-mylongpath-mylongpath-mylongpath-mylongpath-mylongpath-mylongpath-mylongpath"
10
11The patch specifically:
12
13 * Sorts output in GNUmakefile
14 * Always generates indirect flags files used to avoid pathlength issues else the
15 compile commands suddenly change when using longer paths
16 * Sorts the AutoGenTimeStamp file contents
17 * Makes the TargetDescBlock objects from BuildEngine sortable to allow the makefile fix
18 * Fix ElfConvert within GenFw so that only the basename of the binary being converted
19 is used, else the output from "GenFw XXX.bin" differs from "GenFw /long/path/XXX.bin"
20 with sufficiently long paths
