At the beginning of every build, Soong has exported its version of these variables, and has been ensuring that when sorted, the result is the same. So these variables all have the same flags of the Soong ones, but may be in different orders. We don't believe any of the remaining order differences matter. As we remove the Make definitions, the exported Soong variables will take over. This only removes lines that change one of these variables: [2ND_][CLANG_]HOST_CROSS_GLOBAL_CFLAGS [2ND_][CLANG_]HOST_CROSS_GLOBAL_CONLYFLAGS [2ND_][CLANG_]HOST_CROSS_GLOBAL_CPPFLAGS [2ND_][CLANG_]HOST_CROSS_GLOBAL_LDFLAGS [2ND_][CLANG_]HOST_GLOBAL_CFLAGS [2ND_][CLANG_]HOST_GLOBAL_CONLYFLAGS [2ND_][CLANG_]HOST_GLOBAL_CPPFLAGS [2ND_][CLANG_]HOST_GLOBAL_LDFLAGS [2ND_][CLANG_]TARGET_GLOBAL_CFLAGS [2ND_][CLANG_]TARGET_GLOBAL_CONLYFLAGS [2ND_][CLANG_]TARGET_GLOBAL_CPPFLAGS [2ND_][CLANG_]TARGET_GLOBAL_LDFLAGS Many other variables are unnecessary now too, but those will be removed in another change. For those we can ensure the build.ninja file does not change, but we expect it to change here due to the ordering differences. Change-Id: I0bd0778706d02ee27b2784dd8dc6b2c71d37bd3a
