aptでnumpy,scipyを導入時のunreference __fixunstfsi解決
libcompiler_rt.soが7.0.1だと駄目で、7.0.0へ戻す必要ありでした org
pandasまで遠い ( ￣-￣)

$ apt install numpy scipy
$ pip list
Package Version
---------- --------
numpy 1.15.4
pip 18.1
scipy 1.2.0rc1

# 7.0.1は、__fixunstfsiを含まない
apt install libcompiler-rt-termux=7.0.0
cd /data/data/com.termux/files/usr/lib
ln -sf libcompiler_rt-termux.so libcompiler_rt.so
