    • Darwin, Driver - Improve processing of macosx-version-min= · 351ac9c5 
      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).

    • Darwin, testsuite - Adjust two tests that fail on newer OS versions. · 342f8965 
      Newer OS versions (10.14+) do not provide some of the CRTs that are used
for older ones (e.g. 10.5), and thus link tests that specify targeting
such a revision fail.  We retain the testing of the correct defined OS
version number but switch to compile-only testing for these two tests.
