I installed mipsel-linux-uclibc-ldd using `crossdev mipsel-linux-uclibc` and then built a few binaries. Unfortunately, mipsel-linux-uclibc-ldd does not work: # mipsel-linux-uclibc-ldd /usr/mipsel-linux-uclibc/usr/bin/ssh /usr/mipsel-linux-uclibc/usr/bin/dropbearmulti: not an ELF file. `file` indicates otherwise and the binaries work when transferred to my router.
Note that the following versions were installed by crossdev: binutils-2.22.90 gcc-4.6.3 linux-headers-3.5 uclibc-0.9.33.2-r1
uclibc support in Gentoo has been removed.
