I hit an issue when building gtk-doc documentation. The issue is
my fault, but the error output from Meson makes it look like an
internal error:
[0/1] 'Running external command libtracker-sparql-doc.'
Building documentation for libtracker-sparql

After this patch, the output is much clearer:
[0/1] 'Running external command libtracker-sparql-doc.'
Building documentation for libtracker-sparql
Error in gtkdoc helper script:

Note the actual errors from xsltproc are swallowed by gtkdoc-mkhtml
1.25.1, they're only displayed in the example above because I made a
patch: <https://bugzilla.gnome.org/show_bug.cgi?id=774812>
