== ABI implications for our LV2 .so ==
- ELF class/machine we must match: ELF64, AArch64 (verified on both libc and loader)
- OSABI GNU/Linux; kernel minimum per 'for GNU/Linux 3.7.0'
- glibc floor available: 2.36 -> anything requiring <= GLIBC_2.36 loads; > 2.36 will not
- DT_NEEDED libm.so.6/libc.so.6/libdl etc. all present in /usr/lib/aarch64-linux-gnu
