I tried methods (b) and (c) which are not contradictory, then,

Answer to `which mktexlsr' is
/usr/bin/mktexlsr
Now I was suspicious and used `find' and found
/usr/bin/mktexlsr, and
/usr/local/texlive/2012/bin/i386-linux/mktexlsr

I ran both (there may be some bug, there), and checked: 
/usr/local/texlive/2012/texmf-var/ls-R does contain xetex.fmt under 
./web2c/xetex:

I did it from a terminal, and it gave no output at all, which was all I 
hoped.
Then from the terminal, I typed:
xetex test
(my single line test file) and got the answer:
This is XeTeX, Version 3.1415926-2.2-0.9995.2 (TeX Live 2009/Debian)

kpathsea: Running mktexfmt xetex.fmt
I can't find the format file `xetex.fmt'!

??? Before rerunning mktexlsr, but after running mktexfmt, I had tried 
xetex test, and got:

This is XeTeX, Version 3.1415926-2.2-0.9995.2 (TeX Live 2009/Debian)
---! xetex.fmt doesn't match xetex.pool
(Fatal format file error; I'm stymied)

I looked here and there for a file named xetex.pool and could not find it...
All this is very strange.
There may be two instances of texlive, say one in /usr/local and the 
other in /usr/share
but I am not sure whether it is safe to remove every file whose name is 
reminiscent of TeX in /usr/share...
