Previously this test did not check that linking against libpq worked.
This commit fixes that. Besides broken installations this also guards
against pg_config that is applicable to the host when cross-compiling to
Mingw, which doesn't always show up as cross-compiling since some systems
can still run the Mingw binaries if Wine is installed as a binary

gui: Fix File|Export in output viewer.
Commit
f51ecb480 "Greatly simplify PSPP configuration" changed how PSPP
output drivers are configured but failed to completely update the
implementation of File|Export to match. This commit fixes the problem.
A few problems, perhaps not connected, linger:
* The CSV driver appears to always output to "pspp.csv" when invoked
from the GUI, regardless of the requested file name.
* The ODT driver appears to be broken.

gnumeric-reader: Avoid convert_xml_string_to_value segfault on NULL string
If the 'xv' argument is null, the previous version of this code would
still dereference it. This commit rewrites it to instead just set the
value as missing and avoid the segfault. It also takes advantage of the
fairly recently added function value_copy_str_rpad() to eliminate some
code.

FREQUENCIES: Fix corner case for histogram calculation.
calc_stats() assumes that ft->n_valid is nonzero. It has two callers, but
only one of them was checking ft->valid. The other one (which produces a
histogram) is fixed up by this commit.
