Makefile dependency needs updating

[Jerry D. St.Clair]

I see in the ChangeLog that src/gnome-utils/dialog-account-pick.c was
removed as unused.  Make now fails with the following:

...
Making all in po
make[2]: Entering directory `/home/jds/docs/download/dev/cvs/gnucash/po'
make gnucash.pot-update
make[3]: Entering directory `/home/jds/docs/download/dev/cvs/gnucash/po'
make[3]: *** No rule to make target
`../src/gnome-utils/dialog-account-pick.c', needed by
`gnucash.pot-update'.  Stop.
make[3]: Leaving directory `/home/jds/docs/download/dev/cvs/gnucash/po'
make[2]: *** [gnucash.pot] Error 2
make[2]: Leaving directory `/home/jds/docs/download/dev/cvs/gnucash/po'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/jds/docs/download/dev/cvs/gnucash'
make: *** [all] Error 2

Presumably the reference to this source file needs to be removed from
the po Makefile.

Thanks,

Jerry
