    • [Darwin] Pick up SDKROOT as the sysroot fallback. · 24ec3cc9 
      For compatibility with xcrun and the behaviour of the clang driver, make use
of the setting of the SDKROOT environment variable when it is available.
This applies to both finding headers and libraries (i.e. it is also passed to
ld64).

Priority:
 1. User's command-line specified --sysroot= or -isysroot.
 2. The SDKROOT variable when set, and validated.
 3. Any sysroot provided by --with-sysroot= configuration parameter.
 
SDKROOT is checked thus:
  1. Presence.
  2. That it starts with "/" (i.e. 'absolute').
  3. That it is not "/" only (since that's the default).
  4. That it is readable by the process executing the driver.

This is pretty much the same rule set as used by the clang driver.

NOTE: (3) might turn out to be overly restrictive in the case that we
have configured with --with-sysroot= and then we want to run on a system
with an installation of the headers/libraries in /.  We can revisit this
if that turns out to be an important use-case.

So one can do:

xcrun --sdk macosx /path/to/gcc ....

and that provides the SDK path as the sysroot to GCC as expected.

CAVEAT: An unfortunate effect of the fact that "gcc" (and "g++") are
executables in the Xcode installation, which are found ahead of any such
named in the $PATH:

PATH=/path/to/gcc/install:$PATH
xcrun --sdk macosx gcc .... 

does *not* work, instead that executes the clang from the xcode/commmand
line tools installation.

PATH=/path/to/gcc/install:$PATH
xcrun --sdk macosx x64_64-apple-darwinXX-gcc ... 

does work as expected, however.
