This is OK.

This will strip the (debugging) symbols.  You should be using
lily/out/lilypond-bin, unstripped, are you doing that?

Which simply means that LilyPond cannot find /usr/share/lilypond/xyz/afm

Running in gdb is exactly the same as running without gdb.  Just make
sure lily ca find the necessary files.

For developing, you can run lilypond without installing

    ./configure --prefix=$(pwd) --enable-debugging
    make
    gdb ./lily/out/lilypond-bin
