automake: check if the linker supports --dynamic-list
As older versions of gnu ld did not support --dynamic-list check to see
if it is supported before using it. Non gnu linkers such the apple one
likely lack this option as well.
Fixes the build on OpenBSD which has binutils 2.15 and 2.17.
The --dynamic-list option seems to been have introduced sometime after
binutils 2.17 was released as it is present in 2.18.
