[google] Fixing function patching tests (issue5626049)

[harshit at google dot com (Harshit Chopra)]

Fixes the following tests by restricting them to 64-bit target environment.

Tested: Using 'make -k check-gcc RUNTESTFLAGS="i386.exp=patch* --target_board=unix\{-m32,,-m64\}"' and crosstool-validate.py script.

Patch to be applied to google/main branch.

2012-02-03   Harshit Chopra  <harshit@google.com>

  Restricting the tests to run for 64-bit target since function patching
  is only supported for 64-bit targets.
