This will probably work:

make distclean
configure CFLAGS=-g
make

but it seems excessive as you probably only need -fno-crossjumping in xdisp.o.
You could try

rm xdisp.o
make

Do ^C after the compile string is printed e.g

gcc -c -D_BSD_SOURCE   -Demacs -DHAVE_CONFIG_H -DUSE_LUCID  -I. -I/home/nickrob/emacs/src -D_BSD_SOURCE -I/usr/include/alsa -g -O2 xdisp.c
                                            ^^^^^^
edit it like this:

gcc -c -D_BSD_SOURCE   -Demacs -DHAVE_CONFIG_H -DUSE_LUCID  -I. -I/home/nickrob/emacs/src -D_BSD_SOURCE -I/usr/include/alsa -g xdisp.c
                                            ^^
to compile for xdisp.o, then do `make' to get your executable
