The real issue is this:

  libprofiler.so.0: cannot open shared object file: No such file or directory - /<<BUILDDIR>>/ruby-grpc-1.3.2+debian/debian/ruby-grpc/usr/lib/powerpc64le-linux-gnu/rubygems-integration/2.5.0/gems/grpc-1.3.2/src/ruby/lib/grpc/grpc_c.so

I found out that libgoogle-profiler4 does not provide libprofiler.so.0
on ppc64el, while previous versions did:

$ dpkg --contents libgoogle-perftools4_2.5-2_ppc64el.deb | grep libprofiler
-rw-r--r-- root/root    134432 2016-11-27 05:08 ./usr/lib/libprofiler.so.0.4.8
lrwxrwxrwx root/root         0 2016-11-27 05:08 ./usr/lib/libprofiler.so.0 -> libprofiler.so.0.4.8

$ dpkg --contents libgoogle-perftools4_2.6.90-0.1_ppc64el.deb | grep libprofiler
(nothing)
