Update to the 20140208 snapshot of GCC 4.7.4.

Configure with --enable-gnu-indirect-function to enable the "ifunc"
attribute, a GCC extension. [1]

Remove the man7 pages, which we are not packaging, from the staging
area to silence some warnings some are concerned about. [2]

No longer run ccache-update-links as part of post-install which, in
the world of staging, no longer is what it used to be.  Rely on the
existing @exec and @unexec in pkg-plist instead. [3]
