 The micro-revision.i issue is related to buildling SHA sums of lots of
 files and store them in other files. The problem with this is that we
 cd into a subdirectory and use makefile variables (in this case
 noinst_HEADERS) which might refer to files with paths relative to the
 top builddir:

 {{{
     (cd "$(srcdir)" && "@SHA1SUM@" $(src_common_libor_SOURCES)
 $(src_common_libor_crypto_a_SOURCES) $(noinst_HEADERS)) | "@SED@" -n
 's/^\(.*\)$$/"\1\\n"/p' > $@; \
 }}}

 Commit 90d1c857 moves micro-revision.i from src/or/ to the root of the
 build directory. Might be related.


 The missing src/common/crypto.c issue is related to
 src/common/crypto.c not being prepended by the build directory. For a
 comparison with tortls.c:

 Hunting this down further unless someone knows off hand.
