The change in major version (and the increment from Darwin19 to 20)
caused libtool tests to fail which resulted in incorrect build settings
for shared libraries.
We take this opportunity to sort out the shared undefined symbols state
rather than propagating the current unsound behaviour into a new rev.
This change means that we default to the case that missing symbols are
considered an error, and if one wants to allow this intentionally, the
confiuration for that case should be set appropriately.
Three existing cases need undefined dynamic lookup:
libitm, where there is already a configuration mechanism to add the
flags.
libcc1, where we add simple configuration to add the flags for Darwin.
libsanitizer, where we can add to the existing extra flags.

AddressSanitizer and ThreadSanitizer (https://github.com/google/sanitizers) are projects initially developed by Google Inc. Both tools consist of a compiler module and a run-time library. The sources of the run-time library for these projects are hosted at https://github.com/llvm/llvm-project in the following directories: compiler-rt/include/sanitizer compiler-rt/lib/sanitizer_common compiler-rt/lib/interception compiler-rt/lib/asan compiler-rt/lib/tsan compiler-rt/lib/lsan compiler-rt/lib/ubsan compiler-rt/lib/hwasan Trivial and urgent fixes (portability, build fixes, etc.) may go directly to the GCC tree. All non-trivial changes, functionality improvements, etc. should go through the upstream tree first and then be merged back to the GCC tree. The merges from upstream should be done with the aid of the merge.sh script; it will also update the file MERGE to contain the upstream revision we merged with.
