Test suite fixed for Guile 2.0.1

[Ludovic Courtès]

Hello,

I just pushed this fix to 2.12 and ‘master’:

  http://git.sv.gnu.org/cgit/gnutls.git/commit/?h=gnutls_2_12_x&id=ccbd77f6dc0b8440e7d80bddce2c8f950674eb46

It turns out that the unit tests under ‘guile/tests’ were relying on a
long-standing bug, which was fixed in Guile 2.0.1 [0].  With Guile 2.0.0
and 1.8.x, the tests would exit with 0 on success and 1 on failure; with
Guile 2.0.1, they would always exit with 1, which is what the above
commit fixes.

Consequently, using one of the GnuTLS tarball released to date with
Guile 2.0.1 will systematically result in tests failures under
‘guile/tests’.

Thanks,
Ludo’.
