  There's one immediately obvious difference in the generated makefiles between
a bad and a good build:

> -#nodist_finclude_HEADERS = omp_lib.h omp_lib.f90 omp_lib.mod omp_lib_kinds.mod
> +nodist_finclude_HEADERS = omp_lib.h omp_lib.f90 omp_lib.mod omp_lib_kinds.mod

  The good file has the nodist_finclude_HEADERS defined (makes sense), this
adds extra dependencies in the build, and because these files are generated by
running config.status I wonder if there's some kind of either parallel build
missing dependency problem or just a consequence of invoking config.status at a
different time during the build sequence.

  In connection with that, I found an interesting difference when comparing two
config.log files (both from successful builds, as it happens):

@@ -1498,3 +1500,21 @@ toolexeclibdir='$(toolexecdir)/$(gcc_ver
 #define HAVE_SYNC_BUILTINS 1

+This file was extended by GNU OpenMP Runtime Library config.status 1.0, which

as

+  CONFIG_COMMANDS =
+  $ ./config.status Makefile depfiles
+
+on ubik
+
+config.status:1233: creating Makefile
+config.status:1446: executing depfiles commands

  This also makes me think that there's some uncertainty in exactly how and
where config.status is getting run.
