This depends entirely upon how much effort you're willing to invest in

Very... although it would not be safe to try copying the files from
/usr/local/test into /usr due to the tendency of many applications to
hard-code paths. It would more than likely be easier for you to just
keep the source code for the package handy somewhere, and instead of
typing in the commands to build and install it directly, write a short
shell script to do it, so that you can just change --prefix=/usr/local
to --prefix=/usr when you feel certain the new package works properly.

Only you can decide whether or not it's practical, but as to whether or
not it's a good practice... it's not specifically a bad practice, unless
you count deviation from the FHS (which is neither perfect nor
all-seeing) a bad practice.

I think you may have mis-read something. Afaik, glibc never reads
anything under /usr/src/linux, and /usr/src/linux has historically been
a symlink pointing to /usr/src/linux-x.x.xx source that's currently
being used (several other packages do look in there for clues when they
compile). /usr/include/linux and /usr/include/asm*/ on the other hand,
are supposed to be copied from the kernel source that glibc was built
using, and kept there until glibc is next upgraded.
