I don't remember the exact parameters, versions, and compiler I used in
the tests, but here's one example for a relatively small build:

CONFIG_NO_STDOUT_DEBUG=y
CONFIG_NO_AES_EXTRAS=y
CFLAGS += -Os

with gcc 4.1.2 for x86 produced a 61936 byte text segment (68120 bytes
stripped binary size) when using the current 0.6.x version. I remember
getting closer to 50 kB with some other options (and somewhat older
code base), but yes, that was certainly disabling more or less
everything that was not absolutely needed.
