This patch syncs a change to the top-level configury from gdb. It
should not affect the gcc build at all. Tested by rebuilding.

Since we cannot parse the current NeXT headers, because of PR90709 and its
dependents, we have a large amount of testsuite noise for Darwin platforms.
In order to restore the usefulness of the testsuite, we are going add headers
without the modern syntax elements that trigger the bug, and use these for
test runs on newer Darwin.
The headers are imported from GNUStep, with some local modifications to make
sure that __BLOCKS__ is honoured as a gate for Apple-style blocks closures.
CF-CFString.h, F-NS*.h are proxy headers that use the installed CoreFoundation
or Foundation headers on systems <= Darwin12 and the GNUStep headers for newer.

If we compile the openacc testcase with -fopenacc -O2, we run into a SIGSEGV

For PR target/63810 some improvements were made in the parsing of
the version string at the point it's used to define the built-in
__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__. This is fine, but the
specs processing also uses the version, and specs version-compare
doesn't like leading zeros on components. This means that while we
succeed in processing -mmacosx-version-min=010.00002.000099 on compile
lines, it fails for any other line that uses the value as part of a spec
(in particular, link lines fail).
To fix this, we need to apply a bit of clean-up to the version that's
presented to the driver, and push that back into the command line opts.
The value can come from four places:
1. User-entered on the command line
2. User-entered as MACOSX_DEPLOYMENT_TARGET= environment var.
3. Absent those two
3a For self-hosting systems, look-up from the kernel
3b For cross-compilers, as a default supplied at configure time.
We apply the clean-up to all 4 (although it shouldn't really be needed
for the cases under 3).
We also supply a test-case that adapts to the target-version of the
system, so that the link requirements are met by the SDK in use (if you
try to link i686-darwin9 on an x86-64-darwin18 SDK, it will fail).
