Hello Arnout,

I have chroot which was created using buildroot, I'm chrooting into it
an run a simple compilation, e.g sh-4.1# gcc test.c -o test

here is the output gcc -v:
Using built-in specs.
Target: i686-unknown-linux-uclibc
Configured with:
/home/envdev/buildroot/output/toolchain/gcc-4.2.4/configure
--prefix=/usr --build=i686-pc-linux-gnu --host=i686-unknown-linux-uclibc
--target=i686-unknown-linux-uclibc --enable-languages=c
--with-gxx-include-dir=/usr/include/c++ --disable-__cxa_atexit
--enable-target-optspace --disable-libgomp --with-gnu-ld
--disable-libssp --disable-multilib --enable-tls --enable-shared
--disable-nls --enable-threads --with-arch=i686 --with-tune=i686
--disable-largefile
Thread model: posix
gcc version 4.2.4

as for libc.so, here is the relevant output:
sh-4.1# find . -name "libc*"
./lib/libcrypt.so.0
./lib/libc.so.0
./lib/libcrypt-0.9.32.so
./usr/include/bits/libc-lock.h
./usr/lib/libcurses.a
sh-4.1# ls -l ./lib/libc.so.0
lrwxrwxrwx    1 root     root            19 Apr 30 23:57 ./lib/libc.so.0
-> libuClibc-0.9.32.so
