I was wrong. I accidentally build for x86, because TARGET was not set 
when executing

./configure 
--prefix=/home/user/AndroidStudioProjects/GNUnet/distribution/gettext/lib/arm64-v8a 
--host=$TARGET 
--with-libiconv-prefix=~/AndroidStudioProjects/GNUnet/distribution/libiconv/lib/arm64-v8a/

I still have the some issue.

Contents of

~/AndroidStudioProjects/GNUnet/distribution/libiconv/lib/arm64-v8a/

is

/home/user/AndroidStudioProjects/GNUnet/distribution/libiconv/lib/arm64-v8a/
/home/user/AndroidStudioProjects/GNUnet/distribution/libiconv/lib/arm64-v8a/lib

/home/user/AndroidStudioProjects/GNUnet/distribution/libiconv/lib/arm64-v8a/include/libcharset.h

I stripped the share directory.

Architecture of the shared library seems to be ok

file 
/home/user/AndroidStudioProjects/GNUnet/distribution/libiconv/lib/arm64-v8a/lib/libiconv.so
/home/user/AndroidStudioProjects/GNUnet/distribution/libiconv/lib/arm64-v8a/lib/libiconv.so: 
ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically 
linked, with debug_info, not stripped
