Not that I am aware. The orthodox kernel compilation,
cd /usr/src/sys/arch/<name your poison>/conf
config <name of kernel>
cd ..
make clean && make depend && make
<check your work>
make install
does not use /usr/*obj at all, nor anything outside of /usr/src/sys,
(But when you make the raft of kernels with "make release",
/usr/obj is used.)
In the ancient days, many only had the /usr/src/sys hierarchy
installed, since they needed only to roll a custom kernel -- this
made a difference in days of 10MByte main memory and 120MB
disks, and was in fact a necessity. No longer, though, thanks to
sysctl's and related solutions.
A second point, I like to keep /usr/*obj around in case I mess
around with something in /usr/src/ and wish to recompile just
a component. This is handy when a source patch comes out.

I see that's under /usr/src/sys I'd put up with the ?'s. Or maybe
stick .cvsignore files in the obj dirs. potato/potahto.

Each snowflake is unique :)
