Picking another random and small package that uses libz, I see that the 
link does look in work/.buildlink/lib:

attempt to open /usr/pkg/gcc6/lib/gcc/x86_64-redhat-linux/6.4.0/libz.so 
failed
attempt to open /usr/pkg/gcc6/lib/gcc/x86_64-redhat-linux/6.4.0/libz.a 
failed
attempt to open /usr/pkg/gcc6/lib64/libz.so failed
attempt to open /usr/pkg/gcc6/lib64/libz.a failed
attempt to open /usr/pkgsrc/biology/htslib/work/.buildlink/lib/libz.so 
succeeded
-lz (/usr/pkgsrc/biology/htslib/work/.buildlink/lib/libz.so)

I'm assuming I should be seeing the same in gcc8, but I am not, although 
gcc8 does have

.include "../../devel/zlib/buildlink3.mk"

Continuing to investigate, but would appreciate any suggestions.

Thanks,
