It seems possible that the Solaris mkdir is not robust in the face of
a directory being created after mkdir confirmed that the directory did
not exist.  That would at least explain the ``File exists'' error.

The obvious workaround would be to create $(TARGET_SUBDIR) before
calling mkinstalldirs on $(TARGET_SUBDIR)/DIR.  That is what used to
happen--$(TARGET_SUBDIR) used to be created by configure.  Why don't
you try that and see if it fixes the problem.  Alternatively, try
commenting out the code in mkinstalldirs which execs mkdir -p, and see
if that fixes the problem--the mkinstalldirs shell script appears to
be robust.
