get_program_var_addr() must prefer the strong symbol to the weak
one. Search global objects, together with main object and
dependencies, for the requested symbol.

Move the common code from symlook_default() into new helper
symlook_global(), and use it both in symlook_global() and
get_program_var_addr().

Supply lock state to get_program_var_addr().
