The target C library is required of course!  Here the custom glibc for
your custom Linux/mipsel, "Debian", "Broadcomm", "OpenWRT" or 
something... Or use some suitable replacement to bootstrap your GCC.

The 'fixinc' phase tries to fix the target headers, they will also
needed when producing the extra target libs with the new cross GCC,
just as the target libraries in order to investigate its properties.

The place for the target C library is nowadays a (carefully chosen)
$sysroot where the original native install scheme for the target
glibc, X11 libs,  GTK libs etc. can be keeped "as is"...
