Quick explanation: On some systems, DynaLoader defines mod2fname(), which is
used so that each library has a unique name. This is done because some systems
(like Windows, Android, and VMS) only the basename of a library is used by the
linker, which can lead to fairly catastrophic situations; consider Hash::Util
and List::Util -- both of which usually have a library called Util.so -- end up
getting the same library loaded, and mayhem occurs. With mod2fname around,
those two end up being called PL_Hash__Util.so and PL_List__Util.so, which is
far less likely to clash with anything.
The patch below modifies t/7-check-dynaloader.t so that it'll pass on perls
where mod2fname is defined.
