From: Khem Raj <raj.khem@gmail.com>

currently gcc installs a limits.h which references to another
limits.h which it expects from target sysroot and that header
in target sysroot will come from eglibc. So we need to break
this catch-22 and hence we install a self sufficient limits.h
which is then happy when referenced and doesnt complain about
missing limits.h from target sysroot.

This is mostly used when eglibc-initial configure is run
