Many compilers need special flags to compile *.h files as regular
source code, if they will do so at all. Rather than hoping all
compilers will have such a flag and adding mappings for it, create
wrapper .c files for test building single headers.
This allows using the regular rule for compiling C files without the
need for special flags, and it also provides proper dependency tracking
for these objects.

Many of the test programs directly access internal symbols not
exported from the shared libraries. This allows tests to run
when configured with shared libraries.
