So there is an incompatibility here.

Which appears here as well.

It seems you are using cross-compilation? You need to make sure what is
exactly happening actually: does it properly build a 64bit binary etc.
Perhaps you can for instance run

file /lib64/libbrlapi.so* /lib64/libtinfo.so*

I guess you are actually making brltty use a 32bit compiler, and you
need to

export CC="gcc -m64"

before running brltty's configure.
