Hello,
I also seem to have exactly the same issue but I'm totally confused on
how to solve it.I'm using debian testing with GGC 6.2 and GNAT 6.2 and
llvm 3.5 for building the latest version of ghdl source.
This is the output from GCC -v
gcc -v
Using built-in specs.

gcc version 6.2.0 20161109 (Debian 6.2.0-13)
Running the simple adder example provided in the documentation area I
get the relocation R_X86_64_32 error. I've added the extra option
suggested by Tristan on the grt.lst file
@/libgrt.a
-ldl
-lm
-Wl,--version-script=@/grt.ver
-Wl,--export-dynamic
-Wl,-no-pie
-L./
-lz
Is this the right place or have I misunderstood?
Try to add -no-pie instead of -Wl,-no-pie
ghdl -m -v -Wl,-Wl,-v adder

This is a little bit strange as /usr/lib/gcc/x86_64-linux-gnu/6
is in the search path.
Apologies but I'm out of my depth on this. Any help much appreciated.
Would it mean that libgrt needs to be a shared library build with -fPIC
or the ada equivalent?
No, it should work without fPIC (provided that the executable is not pie).
Because this is the first time I post in this list and I'm not very
familiar, is there an easy way to search past entries on this list?
There are archives on gna.org, but a search engine should work too.
This issue is very recent however.
Tristan.
