Clearing CFLAGS_FOR_BUILD, CPPFLAGS_FOR_BUILD and LDFLAGS_FOR_BUILD
from within the recipe looks like it's going to fix it.

  CPPFLAGS_FOR_BUILD = ""
  CFLAGS_FOR_BUILD = ""
  CXXFLAGS_FOR_BUILD=""
  LDFLAGS_FOR_BUILD = ""

It raises some questions though. We setup CFLAGS_FOR_BUILD etc
unconditionally from autotools.bbclass with -isystem pointing to the
native sysroot, but I don't see any default dependency to ensure that
the native sysroot actually contains anything. Should CFLAGS_FOR_BUILD
etc perhaps only be setup for packages which are known to need it,
when we know there's an appropriate dependency in place to populate
the native sysroot?
