ppc64el, Debian unstable:
text data bss dec hex filename
-fpic: 79520 928 1768 82216 14128 postgres_fdw.so
-fPIC: 79520 928 1768 82216 14128 postgres_fdw.so
-> no change
s390x, Debian unstable:
text data bss dec hex filename
-fpic: 80735 2552 48 83335 14587 postgres_fdw.so
-fPIC: 81247 2552 48 83847 14787 postgres_fdw.so
-> +0.61%
arm64, Debian unstable:

sparc64, Debian unstable:

-> 6.9% decrease (!)
9.6.3, gcc (Debian 6.3.0-18) 6.3.0 20170516, -O2, all objects unstripped
(sparc64 is gcc (Debian 6.3.0-17) 6.3.0 20170510)
