Fixes compatibility with GCC-11.
Doesn't require any local patches (all applied upstream or no longer
required).
LICENSE adds three new licenses:
- MIT for code copied from libunwind;
- Apple Public Source License for Mac-specific code;
- BSD-4-Clause also for Mac-specific code.
Since the latter two are Mac-specific, we don't mention them in
_LICENSE.
linux-syscall-support bumped to the verion in DEPS. It now has a license
file so use that instead of the header file.
