dpkg: dependency problems prevent configuration of valgrind:
 valgrind depends on libc6 (>= 2.16); however:
  Version of libc6:mipsel on system is 2.13-38+deb7u11.

Limitations
-----------
- Some gdb tests will fail when gdb (GDB) older than 7.5 is used and gdb is
  not compiled with '--with-expat=yes'.
- You can not compile tests for DSP ASE if you are using gcc (GCC) older
  then 4.6.1 due to a bug in the toolchain.
- Older GCC may have issues with some inline assembly blocks. Get a toolchain
  based on newer GCC versions, if possible.

on router running olsrd:
onetrix@test-router:~$ gdb --version
GNU gdb (GDB) 7.4.1-debian

crosscompile toolchain used:
onetrix@debian7dev:~/valgrind/valgrind-3.13.0$ $CC --version
mipsel-linux-gnu-gcc (Debian 4.4.5-8) 4.4.5
