My final goal was using a .ver file (which is more or less like the symbols
file in our case) and pass that to -Wl,--version-script (instead of the
-export-symbols-regex, which creates such a file on the fly). Then we have a
'symbols' file to maintain/check the api, which is directly passed to the
linker and can also be used for the abicheck.sh test, -Bsymbolic-functions
would've solved the internal PLT stuff. That is the simplest and also the most
effective setup from a performance (whether that is measurable or not) and
maintenance point of view.

Anyway, already restored (and fixed) most of the alias stuff, but I do get a
feeling out of all this that some people don't care because it works for them
and so you don't have to look forward and try something. The performance thing
is an easy one to toss because we all know it is hard to measure, but for that
same bit of extra performance we also use the alias code.
