Build error on 'make tests' for synthetic target

Gentleman,

I am trying to use the synthetic target to do some testing of a
package I am working on. My package has some tests that I would like
to build, but I haven't figured out how to build only the tests for it
and not everything else. If someone could provide some guidance on
that, that would be great.

In the mean time, I tried to just build all of the tests and the build
errored out with the following:

make -r -C infra/current tests
make[1]: Entering directory `/home/mike/ecos-cvs/synthbuild/infra/current'
gcc -L/home/mike/ecos-cvs/synthbuild/install/lib -Ttarget.ld -o

I am running on Ubuntu 10.04.1 LTS. Here is some config info:

Has anyone else attempted building the tests on the synthetic target
or figure out what to do with the error above?
