[uClibc] compiling problem

[Philippe PEZET]

I wanted to compile sane-backends (SANE) latest version tarball under 
uclibc.
compiling with my regular config (glibc-2.3.2) yields a sane daemon 
(saned) of size 4.3 kB.
I downloaded root_fs_i386, mounted it loop, installed sane-backends 
tarball, chrooted to the mounted directory and compiled sane-backends. 
sane daemon (saned) is now 4 MB (yes 4000 kB, and still 1.9 MB stripped) !!!
what am I doing wrong ?
