Bug#888638: firefox: FTBFS on powerpc and ppc64: Error updating ICU data file

[Aaron M. Ucko]

Source: firefox
Version: 58.0-1
Severity: normal
Tags: upstream
User: debian-powerpc at lists.debian.org
Usertags: powerpc ppc64

Builds of firefox for powerpc and ppc64 (the only big-endian
architectures rustc supports at present, and admittedly not release
architectures) have been failing lately.  As of 58.0-1, the
(immediate) errors take the form

  cd build-browser && MOZCONFIG=mozconfig.icu ../mach python ../intl/icu_sources_data.py "/«PKGBUILDDIR»"
  New python executable in /«PKGBUILDDIR»/build-browser/_virtualenv/bin/python2.7

When I tried to reproduce these errors on porter boxes for both
architectures to see what they actually were, I ran into *different*
errors:

  cd build-browser && MOZCONFIG=mozconfig.icu ../mach python ../intl/icu_sources_data.py "/home/ucko/firefox"
  Traceback (most recent call last):
    File "../mach", line 86, in <module>

    File "../mach", line 78, in main

    File "../mach", line 68, in get_mach
      mach = check_and_get_mach(dir_path)
    File "../mach", line 42, in check_and_get_mach
      return load_mach(dir_path, mach_path)
    File "../mach", line 30, in load_mach
      return mach_bootstrap.bootstrap(dir_path)

      module = self._original_import(name, globals, locals, fromlist, level)

      raise Exception('Could not detect environment shell!')
  Exception: Could not detect environment shell!
  debian/rules:205: recipe for target 'stamps/configure-browser' failed

Due to this discrepancy, and the lack of available details for the
autobuilders' failures, I have *not* reported anything upstream here.

Could you please take a look?

Thanks!
