Disable async unwind tables in release buildsupstream/mikhail_no_async_unwind_tables
Add `fno-asynchronous-unwind-tables` option to the release build configuration.
It shaves some bits from .eh_frame binary segment.
From https://gcc.gnu.org/onlinedocs/gcc/Code-Gen-Options.html :
`Generate unwind table in DWARF format, if supported by target machine.
The table is exact at each instruction boundary, so it can be used for
stack unwinding from asynchronous events (such as debugger or garbage collector).`
