I have a follow-up:

In the configuration that led to the above error, I had disabled global
constructors and destructors in the uclibc configuration ("make

If I first try to build with global constructors and destructors
enabled, it eventually gives an error (I think during gcc construction)
about missing __fini_array and __init_array stuff. If I then change the
configuration (using "make uclibc-menuconfig") to disable the global
ctors and dtors and type "make" again, it builds to completion.
Something in that two-step process gets me past the above error about

However, when I try to compile and link a simple flat "hello," the
following happens:

dan at cecilia ~/tmp $ arm-linux-gcc -Wl,-elf2flt hello.c
/mnt/local/armtc/usr/lib/gcc/arm-unknown-linux-uclibcgnueabi/4.3.5/../../../../arm-unknown-linux-uclibcgnueabi/bin/ld.real: error: no memory region specified for loadable section `.ARM.extab'
collect2: ld returned 1 exit status

Does anyone have any idea what I'm missing?
