crosscompile to arm-atmel-uclinux problems

I am trying to bld gettext 0.12.1 to uClinux 2.4 on Arm7tdmi.

I run configure as follows:

$ ./configure --host=arm-atmel-uclinux --prefix=/home/ghessler/uClinux/uClinux-dist/lib --exec_prefix=/home/ghessler/uClinux/uClinux-dist/romfs/usr --with-included-gettext --disable-nls

CFLAGS=-D__linux__ -D__uClinux__ -D__ELF__ -DNO_MM -DCONFIG_CPU_AT75C220=1
        -march=armv4 -mtune=arm7tdmi -nostdinc -fno-builtin -v

When I run make, I get the following undefined errors (and others):
        ../lib/libgrt.a(error.o): In function 'error_tail':
        error.o: undefined reference to 'putc_unlocked'
        error.o: undefined reference to 'fflush_unlocked'

I think I just need to let the linker know how to get the "*_unlocked" functions from uClibc, on
my target.
How do I pass a library dir w/ "-L" to the arm-elf-gcc run from the gettext libtool.
configure blows up when I try to specify -L option.

Thanks for any suggestions,

Glenn Hessler
