Log:
[Darwin, fixincludes] Backport fix for Darwin9/10 TR1 test fails.

Darwin has had long long functions for some considerable time and these are
exposed in Darwin8 and Darwin11+ headers. However, for some reason it was
elected to hide them behind __STRICT_ANSI__ and __STDC_VERSION__ on Darwin9
and Darwin10. This is a problem for G++/libstdc++ that expects the functions
to be available for strict ansi (-std=c++14, for example) and without
defining __STDC_VERSION__. The fix here follows the pattern used in
Darwin11+ headers where the functions may be explicitly hidden by defining
__DARWIN_NO_LONG_LONG.

	Backport from mainline.
	2019-06-21  Iain Sandoe  <iain@sandoe.co.uk>

	* inclhack.def: Replace the complex test using __STRICT_ANSI__ and
	__STDC_VERSION__ with a test using __DARWIN_NO_LONG_LONG.
	Ensure that the top level math.h uses <> to wrap included headers
	rather than "".
	* fixincl.x: Regenerated.
	* tests/base/architecture/ppc/math.h: Update test to include the
	__DARWIN_NO_LONG_LONG case.
