Can you send me gcc's configure line for the sparc toolchain that you use?
Are you using a setup with a gcc/config/sparc/t-* snippet that has FPBIT and
DPBIT not set?
FPBIT =
DPBIT =

t-elf for instance defines:
...
FPBIT = fp-bit.c
DPBIT = dp-bit.c

dp-bit.c: $(srcdir)/config/fp-bit.c
	cat $(srcdir)/config/fp-bit.c > dp-bit.c

fp-bit.c: $(srcdir)/config/fp-bit.c
	echo '#define FLOAT' > fp-bit.c
	cat $(srcdir)/config/fp-bit.c >> fp-bit.c
...

if I can reproduce the error here (if you send the gcc configure line) I
can try to post a patch that handles the error...
