attached some c++ abi comparisions

(the comparision was not entirely clean, it involved
various manual hacks, but most types and functions
should be compared correctly glibc vs musl)

two interesting gcc warnings:

powerpc64 elf_vrreg_t (both musl and glibc):
note: the ABI of passing aggregates with 16-byte alignment has changed in GCC 5

x86_64 struct inotify_event (musl only):
note: the ABI of passing struct with a flexible array member has changed in GCC 4.4
