Just so it's obvious what is happening:

Title:
  Package missing /lib/x86_64-linux-gnu/libgcc_s.so.1, breaks apt-get
  etc.

Status in “gcc-4.8” package in Ubuntu:
  Confirmed

Bug description:
  The latest package available on testing (4.9-20140213-0ubuntu1) is missing the /lib/x86_64-linux-gnu/libgcc_s.so.1 file.
  This causes apt-get to break immediately after apt-get upgrading.
  The package is unusually small:
  -rw-r--r-- 1 root root 1286 Feb 14 09:38 /var/cache/apt/archives/libgcc1_1%3a4.9-20140213-0ubuntu1_amd64.deb
  at only just over 1KB
  The version from packages.ubuntu.com for testing shows as 4.8.2 still, downloading this and dpkg-i'ing the package fixes the issue (until you apt-get update/upgrade again).
  The old version of the file (which is 30+ times larger):
  -rw-r--r--  1 root root     37520 Feb 12 02:38 libgcc1_4.8.2-15ubuntu3_amd64.deb
