I upgraded gnulib in GnuTLS and noticed this problem in a clean
checkout:
jas@latte:~/src/gnutls master$ make syntax-check
No version control files detected; skipping syntax check
jas@latte:~/src/gnutls master$
The reason was that _build-aux was not set when there was no Makefile.
The else-clause of GNUmakefile needs to set the variables the same way
the non-else clause does. I've pushed the patch below.
