Enable building soft float buildroot for gcc 3.3. Currently works for
i386 (limited to 64 bit long double... same as double), arm (libfloat),
mips, and mipsel.
Enable cross compiling a native gcc 3.3 toolchain to run on the target.
Misc rootfs cleanups... strip some things that weren't, eliminate duplicate
libs, move openssl shared libs out of /lib, reduce size of libssl.so
by dynamicly linking with libcrypto.so, fix dropbear compile on mips.
