By default, autoconf will build a binary suitable for valgrind, unless 
you are interested in performance.

In this case, I would advise to build with --enable-build-type=prof.

You will find the meaning of all this in INSTALL.

The symbols will be produced when compiling, no need to get them separately.

Use --with-version-suffix. By default it uses "-2.4.0dev" to the file 
and directories when installing, and uses ".lyx-2.4.0dev" as user directory.

I use --with-version-suffix=-master, so that my user directory is 
~/.lyx-master/.

Hope this helps.
