fix: use readelf with `--lto-syms` in case of LTO #42

Closed haraldh closed 3 years ago

In case LTO was activated, the gnu linker places the symbols in .gnu.lto sections, which readelf prior to 2.36.1 did not understand. Later versions support the --lto-syms option, which is now used for the test-symbols test case.
