[PATCH][GOLD] Enable Cortex-A8 workaround and fix remaining problems.

[=?big5?b?RG91ZyBLd2FuICjD9q62vHcp?= <dougkwan at google dot com>]

Hi,

     This is the final patch for the Cortex-A8 workaround.  It adds
command line options --[no-]-fix-cortex-a8.  If none of them are
given, we look at the architecture attributes to determine if we need
to turn on the workaround at link time.   The main part of the patch
is the code that redirects offending branches to their stubs.  The
rest contains fixes for problem encountered during building of Android
for the Cortex-A8.
