devel/love08: fix build when lld is the system linker

Ports that use openal (such as this one) fail to link with lld as the
system linker due to disagreement in the handling of preemption of
protected visibility symbols in shared objects.

In the case of devel/love08 detected at configure time as:
configure: error: Can't LÖVE without OpenAL
