[I reported the same sort of thing for powerpc64 to the lists back in 2016-Sept
when
devel/powerpc64-gcc was switched over to libc++: -r422765 of /usr/ports/ . This
issue is not unique to 6.2.0 based devel/powerpc64-gcc, nor to 2.25 vs. 2.27
based
binutils. See

https://lists.freebsd.org/pipermail/freebsd-toolchain/2016-September/002357.html

for what I reported back in 2016-Sept (a cross build example).

buildworld targeting powerpc64 aborts reporting:

call to `std::__1::ios_base::Init::Init()' lacks nop, can't restore toc;
recompile
with -fPIC

This is true for cross builds and for on powerpc64 and has been true for some
time.
This example is from on powerpc64.
