Uboot nand_dump testcase

gcc-patches discussion thread:
http://gcc.gnu.org/ml/gcc-patches/2011-12/msg01240.html

During final output of objects, existence of a .text.unlikely section triggers
a section flag mismatch when looking up in the section htab.

More information in mailing list thread, attached are testcases, a larger one
from U-boot, and a very minimal one trying to demonstrate the fail.  (for the
minimal testcase, use -Os/-O2 -mrelocatable to trigger, for the Uboot one add
-ffreestanding)
