@@ -1,17 +0,0 @@
-When looking for a linker, 32-bit clang-cl.exe wants to use the 32-bit-native link.exe located in Hostx86/x86, but this executable does not exist in our releng package, because we only use 64-bit-host toolchains.
-
-This patch makes clang-cl use the Hostx64/x86 linker instead. Ideally we wouldn't be using 32-bit clang-cl.exe in the first place. Bug 1414287 is on file to do so and remove this hack.
