Sure:

(gdb) set environment EMACSLOADPATH 
/vol/src/gnu/emacs/emacs-24.0.90/leim/../lisp
(gdb) b xsignal1
Breakpoint 3 at 0x10294d2c
(gdb) run -batch --no-site-file --no-site-lisp -f batch-byte-compile 
quail/CCDOSPY.el
Starting program: /vol/obj/gnu/emacs/emacs-24.0.90/src/emacs -batch 
--no-site-file --no-site-lisp -f batch-byte-compile quail/CCDOSPY.el
