sys-libs/glibc: Apply Flatcar modifications

Browse Source 
- take care of nscd.conf via tmpfiles, add files/nscd-conf.tmpfiles.
  - comment out 'dostrip -x' to force the OS image binaries to be stripped
  - remove everything glibc wants to put under /etc since we use
    baselayout to provide that
  - add a fix for cross-prefix

# GLibc
The system's C library, sometimes referred to as "service pack for the C
language". The build recipe has a single modification over the one Gentoo
upstream uses: in the installation callback `glibc_do_src_install`, we remove
all of glibc's `/etc` files right after the stock glibc build diligently
installed them, since we ship our own `/etc` stuff via the `baseimage` recipe.
The addition sits at the end of the `glibc_do_src_install` function and is duly
labelled `## Flatcar Container Linux: ...`.
