/* Relocations against Thumb function names must be left unadjusted,
so that the linker can use this information to correctly set the
bottom bit of their addresses. The MIPS version of this function
also prevents relocations that are mips-16 specific, but I do not
know why it does this.
FIXME:
There is one other problem that ought to be addressed here, but
which currently is not: Taking the address of a label (rather
than a function) and then later jumping to that address. Such
address also ought to have their bottom bit set (assuming that
they reside in Thumb code), but at the moment they will not. */
