ElfKit _should_ be producing dynamically linked executables.
Hmm ... Except on FreeBSD-current, the "file" command does not report
whether an ELF file is dynamically linked or not. For example, on a
dynamically-linked ELF file "hello", the -2.2 "file" command says:
hello: ELF 32-bit LSB executable, Intel 80386, version 1 (FreeBSD)
The same command on a -current system says:
hello: ELF 32-bit LSB executable, Intel 80386, version 1
(FreeBSD), dynamically linked, not stripped
(on a single line).
At first, I thought you had a dynamically linked program but did not
realize it. But ...

47761 bytes is much too large (my "hello" is only 4121 bytes even
before stripping it). So I think you really are getting a statically
linked executable, for some reason.
Are you sure your ELF shared libc is installed properly? You should
have this in /usr/local/elf/i386-unknown-freebsdelf/lib:
lrwxr-xr-x 1 root bin 9 Apr 16 1996 libc.so -> libc.so.3
-rwxr-xr-x 1 root bin 404921 Apr 15 1996 libc.so.3
If that looks OK, then please run the following command, and send me
the output it produces:
elf-cc -v -o hello hello.c
Thanks,
John
