libubacktrace: use -asynchronous-funwind-tables rather than -funwind-tables
From gcc documentation, we can read:
" ...
-fasynchronous-unwind-tables
Generate unwind table in dwarf2 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)
..."
So it seems better rather than using -funwind-tables (glibc seems to prefer
-fasynchronous-unwind-tables).
