Thanks.

Well, I did it and am doing an emerge -e world now.  (I'm trying the new 
still-masked gcc-4.2.0, and hadn't done an emptytree emerge world for 
some time, so it's a good idea even if it wasn't really required for the 
profile change.)

It wasn't a tenth as bad as I thought it might be.  Other than the masks, 
most of which are 32-bit binary-only stuff anyway, so not anything I'd 
have merged in the first place, there's very little in that specific 
subprofile, much less than I initially thought, as most stuff is 
inherited from the cascade, and thus was common to both the old and new 
profiles.

After doing the actual symlink switch, I ran an emerge -pN world and only 
four USE flags changed state, all of which I wanted to keep as they were 
(I generally pay pretty close attention to such things, so have my flags 
set the way I want them), so that was four additions to my /etc/portage/
make.conf/use file.  (My make.conf is simply a number of includes, 
cflags, ldflags, use, features, fs, makeopts, net, log, mirrors, custom, 
other, all included files located in /etc/portage/make.conf/* with only 
the appropriate settings in each of them.  Easier maintenance that way.)

I had actually already done an emerge -e system after switching to the 
new gcc, and ran into problems compiling 32-bit sandbox, so used emerge --
resume --skipfirst on it to finish the system class.  Thus, I only had to 
remerge sandbox, gcc, glibc, and eselect-opengl, to kill all the entries 
that had existed in equery b lib32 and pretty much all my 32-bit stuff.  
I remerged baselayout just to be safe, before hand deleting the .keep 
files and lib32 dirs.

After killing grub and merging grub-static, and recompiling the kernel 
(which I hadn't yet done with gcc-4.2.0, as I do it using my own scripts, 
outside of portage) it was time to start the emerge -e world, which is 
now underway, a total of 608 packages to remerge, 580 or so to go...

So, everything seems fine so far. Nice not to have to worry about that 
stupid 32-bit stuff, either the dirs or the problems it seemed to bring 
every so often, any more.  =8^)
