Hi Fan,

Thanks for catching this. However since the typo is in an exported API,
we can't simply change it to the right spelling, as that would break
library compatibility, cause an soname bump (which we try to avoid).

A solution would be to /add/ the fixed spelling version of the api
alongside the misspelled one. Would you like to take a crack at doing
that instead?

Note that for the new API, the libcxl.sym addition will need to go into
a new section at the bottom instead of alongside the old one.
