I agree.

However, in this case the question is why is it picking up all that stuff 

The relocation is only used in the case of the groff-local localcharset.c being
It's only a fallback that is used if glibc < 2.1.  I've checked the guix build
logs, the glibc version is newer and also found by the 'configure phase of 

I can't tell about groff-minimal because the build log as given by
"guix build --log-file groff-minimal"
has 0 Bytes.

Anyway, a simple way to disable this weird relocation business would be to 

./src/libs/libgroff/Makefile.sub:             -DENABLE_RELOCATABLE=1 \

However, it would be preferrable to find out why 
(the only user of it) is used at all.  It really shouldn't be.
