boost stacktrace broken on solaris

[dkimura@…]

Solaris dladdr doesn’t match function signature of most platforms nor the signature expected in boost stacktrace sources.

Solaris: int dladdr(void* addr, Dl_info* info);
Darwin: int dladdr(const void* addr, Dl_info* info);

This caused the following build errors on Solaris SPARC and Solaris X86.

location_from_symbol.hpp, line 31: Error: Cannot cast away const or volatile.
location_from_symbol.hpp, line 31: Error: Formal argument 1 of type void* in call to dladdr(void*, dl_info*) is being passed const void*.
frame_unwind.ipp, line 87: Error: Cannot cast away const or volatile.
frame_unwind.ipp, line 87: Error: Formal argument 1 of type void* in call to dladdr(void*, dl_info*) is being passed const void*const.

Following diff seems to fix this issue:
