For the test to succeed there needs to be some header that is to be found in
the 'expected' place i.e. <sysroot>/usr/include/. It's important that it is
not the name of a header for which fixincludes have been applied, since such
headers will be found in the gcc include-fixed dir and, in general, reference
additional headers. The dummy sysroot will prevent the additional headers
from being found, resulting in a failed test. The fix is to use a header name
that isn't expected to be present in a real sysroot.

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.
Use the CF-CFString.h, F-NS*.h proxy headers where needed in the objective-c
testsuite. Make minor adjustments to tests as required, providing that those
do not alter the test intent.

The testcase is failing to instrument part of the source because of a bug
in the ordering of static DTORs. It seems unlikely that this is generically
fixable in the toolchain (and given that it's likely to be a dynamic loader
change would not be expected to be applied retrospectively to OS versions
that are out of support). To avoid the testsuite noise, xfail the count lines
that don't match (we can adjust the xfails as/when the upstream bug is fixed).
dejagnu xfails do not seem to work when embedded in a line like:
~Test (void) { .... /* count(1) { xfail ... } */ }
the closing brace seems to confuse the parser. The solution is to exapnd the
text onto three lines.

Gnatlink has code that checks for duplicate '-shared-libgcc’ switches (but not
duplicate ‘static-libgcc’) and also pushes ’static-libgcc' onto the link line for
targets that default to static linking, provided '-shared-libgcc' is not present.
For targets that should use a shared libgcc we need the same process to be
applied (in inverse), in the event that they do not default to providing the
shared flag implicitly.
So this adds the complementary set of tests for the shared case and pushes
the shared flag as needed. As a minor tidy-up there’s no need push duplicates
of the libgcc switch onto the link line when one has already been seen (given by
the user).
The patch does not alter any of the platform defaults for static/shared libgcc,
but it ensures that the intent of the link is explicit.
