build: don't add libraries when --enable-static

Currently when building with --enabled-static the cctest target will
include libraries to be linked regardless. This commit adds a condition
to only add the libraries when dynamically linking.

This commit re-adds the previously reverted commit (be63c26
"build: don't add libraries when --enable-static"). The reason that
commit failed was a mistake on my part where I moved the the list
into a variable (thinking that it was a simple change that would not
affect anything) and not re-running CI. But the list itself contains
variables used to enable differences in operating systems/compilers
where the object file locations vary.
