From 77c3e6a4aaed07e626f4bf4deb7eb66e0f03a33d Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix two errors when cross-compiling with Vala

- AttributeError: 'ValaCompiler' object has no attribute 'get_program_dirs'

  Fixed by adding a `get_program_dirs()` function to the base Compiler
  class, to match `get_library_dirs()`

- KeyError: 'vala_COMPILER'

  Fixed by creating the Vala compile rules for all machines, not just
  the build machine.

Upstream-Status: Backport [https://github.com/mesonbuild/meson/commit/77c3e6a4aaed07e626f4bf4deb7eb66e0f03a33d]
