Not sure how you find out I used libtool build. In my configure option, 
I did specify "--without-libtool".

Here is the output from configure about compiler and libtool:

/C compiler:                gcc -DHAVE_AVX_AT_COMPILE_TIME 
-DHAVE_SSSE3_AT_COMPILE_TIME -DHAVE_SSE_AT_COMPILE_TIME -g -O2 -fPIC//
//  C++ compiler:              g++ -std=c++11 -DHAVE_AVX_AT_COMPILE_TIME 
-DHAVE_SSSE3_AT_COMPILE_TIME -DHAVE_SSE_AT_COMPILE_TIME -g -O2 -fPIC//
//  C++14 support:             no//
//
//  LIBTOOL support:           no/
