Sorry, not so long as bug#63995 exists.

Note the following in configure.in attempts to do this kind of thing already:
# Now get this: Some word that is part of the ${srcdir} directory name
# or the ${configuration} value might, just might, happen to be an
# identifier like `sun4' or `i386' or something, and be predefined by
# the C preprocessor to some helpful value like 1, or maybe the empty
# string. Needless to say consequent macro substitutions are less
# than conducive to the makefile finding the correct directory.
[cpp_undefs="`echo $srcdir $configuration $canonical unix |
sed -e 's/[^a-zA-Z0-9_]/ /g' -e 's/^/ /' -e 's/ *$//' \
-e 's/ */ -U/g' -e 's/-U[0-9][^ ]*//g'`"]
so it's not obvious to me why you need to do more (maybe $canonical is
i686-something but your directories are i386-something?).
