Comment (by jmaki):

 Switching to link-style 'static_pic' in buck fixes the issue. Difference
 to "repro":
 {{{
 -ghc -no-link -package-name foo -i Foo.hs -Wall -Werror
 +ghc -fPIC -dynamic -hisuf dyn_hi -no-link -package-name foo -i Foo.hs
 -Wall -Werror

 -ghc -no-link -package-name bar -package-db ../foo/pkg -package foo \
 +ghc -fPIC -dynamic -no-link -package-name bar -package-db ../foo/pkg
 -package foo-1.0.0 \
     Bar.hs
 }}}
