Try: ghdl -e -v foo, you should have the linker command line.
Was GHDL built with gcc ?
I made a mistake in the original post - the GHDL version I'm using is tip
(which will become 0.32rc2 (?)). It's built with and into gcc-4.9.2 - the
gcc-aux port on FreeBSD-10.1
(https://www.freebsd.org/news/status/report-2013-07-2013-09.html#FreeBSD-Ada-Ports).

Now that you have the complete linker line, try to find the offending
option or library.
GHDL doesn't create a DSO, so there is something strange. Try without
the --export-dynamic and/or --version-script.
collect2: error: ld returned 1 exit status
ghdl: compilation error
From this, I notice two slashes in some of the paths: ".../4.9.2/vhdl//v93/..."
^^
Probably not related to the current problem, but interesting.
This s harmless.
Tristan.
