If you try running

mipsel-uclibc-gcc -I. -I./libtomcrypt -I./zlibincludes -I../zlibincludes -Os -W -Wall -DDROPBEAR_SERVER -DDROPBEAR_CLIENT -DDBMULTI_dropbear -DDBMULTI_dbclient -DDBMULTI_dropbearkey -DDBMULTI_dropbearconvert -DDBMULTI_scp -DDROPBEAR_MULTI dbmulti.c -E 

you'll get the preprocessed source, which should have
annotations where the header files are coming from? If
utmpx.h is only in the bits/ subdirectory, then it shouldn't
be getting defined as existing by configure. Perhaps hunt
about in config.log and see what path it's searching or
something?

I don't think you should be using the bits directory
explicitly.

Firstly, sure you don't mean --with-zlib (missing '-')?

If that's not the problem, try with
--with-zlib=/dl/Skymesh2/MIMO_GPL_1.00.06/src/router/dropbear/zlib , and put
the headers in
/dl/Skymesh2/MIMO_GPL_1.00.06/src/router/dropbear/zlib/include
and the libraries in
/dl/Skymesh2/MIMO_GPL_1.00.06/src/router/dropbear/zlib/lib

Let me know how it goes, sorry for the delay in replying.
