Bug#855076: giac: FTBFS: .../giac-doc/...: No such file or directory

[Aaron M. Ucko]

Source: giac
Version: 1.2.3.25+dfsg1-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Builds of giac covering only its architecture-dependent binary
packages have been failing:

  find debian/giac-doc/usr/share/giac/examples/ \
    \( -name '*.cas' -o -name '*.xws' -o -name '*.cxx' \) -exec chmod -x '{}' \;
  find: 'debian/giac-doc/usr/share/giac/examples/': No such file or directory
  debian/rules:26: recipe for target 'override_dh_fixperms' failed
  make[1]: *** [override_dh_fixperms] Error 1
  make[1]: Leaving directory '/«BUILDDIR»/giac-1.2.3.25+dfsg1'
  debian/rules:7: recipe for target 'binary-arch' failed
  make: *** [binary-arch] Error 2

(On some architectures, the build fails earlier, due to unrelated
issues I'll report separately.)

Please conditionalize the debian/rules commands that work with
giac-doc appropriately, for instance by renaming override_dh_fixperms
to override_dh_fixperms-indep.

Thanks!

FTR, even though giac is new to Debian, I'm classifying this bug as a
regression because it would affect potential binNMUs.
