Description

I discovered by symbol sleuthing that even if the Brotli shared libraries are available on the system, the static libraries will be used for linking. Here's a dump of the symbols on my machine

https://gist.github.com/wesm/b7e911424ce3ca3a175b652666fe6f89

The largest of these symbols kBrotliDictionaryData is 120KB

Since we statically link everything in our Python wheels, we might consider disabling Brotli in manylinux builds at least since it adds 800KB to libarrow.so
