Weak functions don't work well with static libraries and require the use of
"whole-archive" flag to ensure that the correct function is used when
linking. Since the weak functions are only used as placeholders within
this library alone, we can replace them with non-weak functions using
preprocessor ifdefs.

This will also need -Wno-uninitialized (otherwise it will generate
warnings about the search_neon_4 and search_neon_8 functions).

But I don't like papering over these conversions.  I'd prefer instead
the patches I posted at:

http://mails.dpdk.org/archives/dev/2019-April/129540.html
and
http://mails.dpdk.org/archives/dev/2019-April/129541.html

Are you opposed to merging those?

I think I have a solution for this that can use the weak aliasing and
not require the use of the whole-archive flag.  Would you prefer that?

Nope, not in the least. I'm happy enough to rework this patch on top of
those - I'd just had forgotten about them in my rush to get a potential
solution out here.  I did these up quickly to show how easy it is to remove
the need for the weak functions and the subsequent linker "--whole-archive"
flag.

/Bruce

PS: I see your patch 2 does not include the Wno-uninitialized flag, is it
not needed in your patch, or just an oversight?

It isn't needed, I resolved the issue with an explicit initialization.
