That's the thing, make.profile technically *is* a directory -- a symlink to
one.  The original design of make.profile was to specify generic, base
settings for a given profile and keep that in the tree.  Things like default
CHOST, default ARCH, default <VARIABLE>, etc.  make.conf then overrides
in-tree settings with settings specific to your system.  So making
/etc/make.profile an actual directory disconnects it from the tree, which I
don't think will work very well for Portage, since it won't know what your
currently-chosen profile is.
