Enviornment: Fedora 15 
I downloaded buildroot-20110603.tar.bz2, unzipped it, only saved directly to
use the default values in menuconfig. Then do a simple "make". I got a compile
error when compiling binutils-2.21, the error is:

# gcc >= 4.3.0 have to also build all-target-libgcc
/usr/bin/make -j2 -C
/home/haibo/learn/buildroot/output/toolchain/gcc-4.3.5-intermediate all-gcc

Checking multilib configuration for libgcc...

I could work around this problem by doing the following:
$cd /usr/lib
$rm libc.so
$ln -s /lib/libc.so.6 libc.so

But this is not the best way, because ASCII file /usr/lib/libc.so's missing
incurs other problems, fox example "make menuconfig" fails to launch
