I had originally worked around this problem in some other package that 
used recursive configure scripts by doing something like:

CONFIGURE_ENV+= CPPFLAGS="${CPPFLAGS:M*}"

which seemed to strip out extra whitespace at the front and in-between 
options passed via CPPFLAGS.  I think in the new way that variables are 
being passed to configure and make via ALL_ENV, the same workaround 
would look like:

ALL_ENV+=       CPPFLAGS=${CPPFLAGS:M*:Q}

Todd, I'm not completely up-to-date on the changes that you've been 
making over the past few months to have variables are set and passed. 
Could you verify that this is conceptually and syntactically correct?

        Thanks,
