Yes and no: `No', because you probably want to use the new
`texinfo.tex' file for other projects also (see below). `Yes',
because the `texinfo.tex' version from the lilypond's `texmf'
directory is actually used while compiling lilypond's documentation.

======================================================================
Somewhere on your harddisk you have a complete TeX installation
which allows access to various TEXMF trees. For example, if I say
kpsexpand '$TEXMF'
on my GNU/Linux command line to look up the value of the `TEXMF'
variable[1], the following gets returned:
{
/home/wl/.texlive2012/texmf-config,
/home/wl/.texlive2012/texmf-var,
/home/wl/texmf,
!!/usr/local/backup/TeXLive/Master/texmf-config,
!!/usr/local/backup/TeXLive/Master/texmf-var,
!!/usr/local/backup/TeXLive/Master/texmf,
!!/usr/local/backup/TeXLive/Master/../texmf-local,
!!/usr/local/backup/TeXLive/Master/texmf-dist
}
Files are searched in this directory order. Note that each of those
directories is a TDS (TeX Directory Structure) tree which has a
standardized structure,
cf. http://ctan.open-source-solution.org/tds/tds.html#Summary for a
summary of its layout. TDS trees are also called TEXMF trees.
I haven't modified the TEXMF variable in my environment, thus you see
the original values as distributed with TeXLive 2012. The first two
lines are the configuration directories maintained by TeXLive itself,
mainly to store generated files. The third one is my personal TEXMF
tree. The directories which names start with two exclamation marks[2]
are considered read-only on my harddisk, holding the data provided by
TeXLive itself. (My layout is a bit odd probably since I'm running
TeXLive directly from the SVN.)
To summarize:
. Additional packages intended for global use should be stored in a
`texmf-local' tree. The emphasis lies on *addition*; it should
rather not be used for replacement files: As you can see above,
the `texmf-local' gets searched *after* `texmf' by default. This
can be changed, but I don't recommend this.
. Replacement files are best located in your personal TEXMF tree.
Since TeXLive comes with `texinfo.tex', you should go this route.
If I say
kpsewhich texinfo.tex
I get
/usr/local/backup/TeXLive/Master/texmf-dist/tex/texinfo/texinfo.tex
thus an appropriate location for the new file would be
/home/wl/texmf/tex/texinfo/texinfo.tex
on my harddisk. Consequently, I could say
make TEXMF=/home/wl/texmf install-tex
to install texinfo's tex files. This make call automatically
creates all necessary subdirectories, BTW.
[1] This environment variable is used internally by the TeXLive's path
finding system, provided by the kpathsea library.
[2] `!!' means that one or more TeXLive cache files called `ls-R'
should be looked up exclusively instead of doing an actual disk
search.
