* New member "archiveMemberName" for struct _ObjectCode
struct _ObjectCode should be able to retain the name of archive members.
Though currently the only use of those names are for debugging outputs.

* FIX #1845 (unconditional relative branch out of range)
Don't use mmap on powerpc-apple-darwin as mmap doesn't support
reallocating but we need to allocate jump islands just after each
object images. Otherwise relative branches to jump islands can fail
due to 24-bits displacement overflow.
