Investigate why Linux/Android can't use DebugDescriptionMacro

[etcwilde]

Description

The DebugDescription macro bits of swiftCore is hard-coded to be removed when building for Linux and Android with the comment:

# Freestanding and Linux/Android builds both have failures to resolve.

We should understand why and get it enabled everywhere.

swift/stdlib/public/core/CMakeLists.txt

Lines 271 to 274 in e4e0760

	# Freestanding and Linux/Android builds both have failures to resolve.
	if(NOT BOOTSTRAPPING_MODE STREQUAL "OFF" AND NOT SWIFT_FREESTANDING_FLAVOR AND NOT SWIFT_HOST_VARIANT_SDK STREQUAL "LINUX" AND NOT SWIFT_HOST_VARIANT_SDK STREQUAL "ANDROID")
	list(APPEND SWIFTLIB_SOURCES ObjectIdentifier+DebugDescription.swift)
	endif()
