Revert "libstdc++: Horrible macro hacks to allow building on avr"

This reverts commit 061700c9f6f0f9f4219ddeb236d55764b42869b6.

This hack will be unnecessary, as I'm backporting the __unsupported()
utility from the later branches.

libstdc++-v3/ChangeLog:

	* src/c++17/fs_ops.cc (not_supported):
	* src/filesystem/ops-common.h (ENOTSUP):
