  "message": "gn: Diag on distinct toolchains with the same name.\n\nPreviously, toolchains with the same name used to silently write to the same output\ndirectory and clobber each others generated .ninja files.  After this patch, this still\nhappens, but gn writes an error message while writing the final build.ninja file.\n\nExample output:\nERROR at //build/toolchain/mac2/BUILD.gn:51:3: Duplicate toolchain.\n  toolchain(target_name) {\n  ^-----------------------\nTwo or more toolchains write to the same directory:\n  //out/gn1/clang_x64/\n\nThis can be fixed by making sure that distinct toolchains have\ndistinct names.\n\nSee //build/toolchain/mac3/BUILD.gn:51:3: Previous toolchain.\n  toolchain(target_name) {\n  ^-----------------------\n\nDepends on https://codereview.chromium.org/2485523002/\n\nBUG\u003d661054\n\nReview-Url: https://codereview.chromium.org/2483713003\nCr-Original-Commit-Position: refs/heads/master@{#430473}\nCr-Mirrored-From: https://chromium.googlesource.com/chromium/src\nCr-Mirrored-Commit: eab6e2d58dc3b71e094ff58d822980ca3473caf8\n",
