1352bc88a0 Darwin : Update libtool and dependencies for Darwin20 [PR97865] 
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.

libcc1/ChangeLog:

	PR target/97865
	* Makefile.am: Add dynamic_lookup to LD flags for Darwin.
	* configure.ac: Test for Darwin host and set a flag.
	* Makefile.in: Regenerate.

d1339b519a libbacktrace, Mach-O : Support PowerPC archs. 
This adds the PPC architecture variants for Mach-O libbacktrace.

With this (as for X86 and Arm) when dsymutil is run on the binary
we get a basic usable backtrace.

Testsuite results on powerpc-apple-darwin9 are the same as for X86:
 * btest fails (TBC why)
 * dwarf5 tests fail because dsymutil does not handle that so far.

0755f573f0 libbacktrace: avoid ambiguous binary search 
Searching for a range match can cause the search order to not match
the sort order, which can cause libbacktrace to miss matching entries.
Allocate an extra entry at the end of function_addrs and unit_addrs vectors,
so that we can safely compare to the next entry when searching.
Adjust the matching code accordingly.

Fixes https://github.com/ianlancetaylor/libbacktrace/issues/44.

4c1a5d8b71 x86: Also check if -fcf-protection works 
When defaulting CET run-time support to auto, check if -fcf-protection
works.  Even if the stage1 GCC doesn't support -fcf-protection, since
the final GCC does, CET run-time support will be enabled by default if
binutils support CET.
