To implement the optimization described in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43129, we need to represent the
offset from a code label to a global variable's GOT entry. This can be
implemented through the arm relocation R_ARM_GOT_PREL. But currently we can't
represent it according to
http://sourceware.org/binutils/docs-2.20/as/ARM_002dRelocations.html#ARM_002dRelocations.
