I have thought about it again. For other sections, the mapping is
as follows:
	.xxx -> .ARM.exidx.xxx

So, if there is an ".ARM.exidx.text", it must be from ".text", and adding
".ARM.exidx.text" will not cause any other harm. We only need
to ensure that the merging of the ".text*" sections is consistent
with the merging of the ".ARM.exidx*" sections, and the current patch
already satisfies this requirement.

I have no other questions about this, so:
