This will generate code with an B<xs_init> function that glues the perl B<Socket::bootstrap> function

Note that B<DynaLoader> is a special case where it must call B<boot_DynaLoader> directly.
When looking for B<DBD::Oracle> relative to a search path,
we should find B<auto/DBD/Oracle/Oracle.a>

In addition, when ModuleName.a is found, additional linker arguments
