It comes from GDAL in port/cpl_cpu_features.h/.cpp . I did some change in that 
area a few weeks ago. There's some subtelty to inline it or not, depending on 
the compiler, etc, but everything works fine on environments tested by 
continuous integration.
What is your compiler and compiler version ?

Hum, what surprises me is that in a previous post you mentionned having built
--without-libtool, but here you link agains a libtool build. If you indeed use 
a non-libtool build, you need to remove the /scratch/gdal/gdal/gdal/.libs 
directory
