   4 Subject: [PATCH] Include environment variable GCC_HONOUR_COPTS in hash.
   5
   6 The OpenWRT patch, 910-mbsd_multi.patch, to GCC adds an extra
   7 compilation flag, -fhonour-copts, which is influenced by an
   8 environment variable called GCC_HONOUR_COPTS.
   9
  10 Include this environment var in the hash calculation as otherwise
  11 the gcc stdout warning from a previous compilation might be shown
  12 where, even when GCC_HONOUR_COPTS is in 's'ilent mode.
