Commit 35e038c1d2 started to use an
incomplete list of subdirs based on $(all-subdirs) causing
testroot.pristine to miss files from nss.
Tested if the list of files in testroot.pristine remains the same.
[BZ #24794]
* Makeconfig (all-subdirs): Improved source comments.
* Makefile (testroot.pristine/install.stamp): Pass
subdirs='$(sorted-subdirs)' to make install.
