gprofng/testsuite: adjust linking of synprog
In order for so_syn.so and so_syx.so to be able to access the main
program's "testtime" variable, that variable needs exposing in the
dynamic symbol table. Since this is a test program only, do it the brute
force way and simply expose all global symbols.
